You probably have an undefined reference, such as a variable or procedure name. Check for misspellings first.

You may be referencing an item out of scope, or not in your current namespace. Maybe you're calling a function from an external library which is not linked in.

If you want to post the offending code, maybe I can give you more details.

Press numbers display syntax error how solve a problem?


The order in which you are entering numbers and operations is not correct. For example, if you enter 5++2 most calculators will flag this as a syntax error.
On some calculators you calculate square roots as follows: 25 [SQRT]= gives 5. That is the correct syntax for this type of calculators.
For the newer ones you press the SQRT key and see displayed the square root symbol followed by a left parenthesis. You enter the number, close the right parenthesis, then =. If you do not respect the order you get a syntax error.
I cannot say more because I have no idea what you were trying to do, and more importantly, I do not know the make and model of the calculator.

Cannot view my own website. it reads: "Parse error: syntax error, unexpected $end..." in my index.php file. HELP


Syntax errors are the most common problem for developers. A single syntax error can cripple even the best applications and websites. You can correct syntax errors easily once you find them. Typical errors include missing commas, semicolons and parenthesis. Debuggers are available in many software development kits to aid you in the location of syntax errors. However, you can find and correct syntax errors manually as well. Learning how to correct syntax errors is an essential part of being a software developer.

Locate the syntax error manually. Step through each section of your code. Most code will be sectioned off into groups or functions. Carefully proof your code. Be sure to pay close attention to how lines are grouped. A common syntax mistake is incorrect grouping.

For instance, if you have an If Else statement embedded in another If Else statement, be sure the embedded statement is surrounded by a separate set of parenthesis or brackets, depending on your language. Double-check notes sections. Notes are only for the developer to see. However, if the syntax isn't correct, the notes may become part of your application, which may not agree with existing code. Ensure the syntax around your notes is correct. Run a debugger if possible. This will make locating errors much easier. A debugger will be found under a menu such as Debug, Run or Tools or as part of your SDK's toolbar. Allow the debugger to run. Errors will be listed at the bottom or right side of your screen. Many debuggers will highlight possible errors in your code as well. A line number, along with the possible error, will be listed in the error message. Locate your syntax error if the debugger isn't correct. Sometimes a debugger will show you where your application stopped working correctly. The syntax error itself may be above or below the line listed in the debugger message. Check all syntax within the surrounding area, especially within the line's function. Run your application after correcting the syntax error. Check every possible function of your application to ensure it works correctly. If you find a problem, double-check the syntax in your code that surrounds the problem area. For instance, if your application has a log-in screen that isn't accepting passwords correctly, check the code for the log-in screen. Remove Syntax Error syntax error typically occurs when the Web page you are loading causes a script error in the browser. This is caused by incorrect code that displays an error message or results in a Web page that does not load correctly. You can remove a syntax error by making a change to the settings of your Web browser. Common Web browsers that can experience this type of error include Internet Explorer, Mozilla Firefox and Safari.
Double-click the "Internet Explorer" icon to open the program. Click the "Tools" drop-down menu and select "Internet Options." This will display the Internet Options window. Go to the "Advanced" tab and scroll down to the "Browsing" section. Remove the check from the box for "Disable script debugging (Internet Explorer)," "Disable script debugging (Other)" and "Display a notification about every script error." Click the "Apply" button to save the changes. Click the "OK" button to close the Internet Options window. Close and restart the Internet Explorer browser for the changes you made to take effect. b> Mozilla Firefox b> Double-click the "Mozilla Firefox" icon to open the program. Type "about:config" into the address bar and press the "Enter" key. Type "dom.max_script_run_time" into the Filter text box and press the "Enter" key. Double-click "dom.max_script_run_time" to display the Enter Integer Value dialog box. Enter a value of "10" or "15" into the text box and click the "OK" button to save the change. Close and then restart the Firefox browser for the change to take effect. b> Safari b> Click the "Safari" icon to open the Web browser. Select the option for "Preferences" from the menu bar. Go to the Advanced tab and click the option for "Show Develop menu in menu bar." Click the option for "Develop" from the menu bar. Click the option for "Disable Runaway JavaScript Timer." Close and re-open the browser for the change to take effect.

VBScript compilation error ''800a0408''


The Symptoms you get The script does not execute as you had hoped. Instead you get a WSH message box.
The Cause of error 800A0408 Your VBScript contains an illegal character, often at the beginning of a line. It can happen if you copy the script from word, then paste into notepad. For example, to 'Rem out a line we need the apostrophe, which is ASCII character 39; however if you paste from word you may get ASCII 96 (Grave accent).
Note the clue Source: Microsoft VBScript compilation error, this means a syntax error in your script.
The Solutions Check the punctuation marks in your VBScript, particularly look out for apostrophes and commas that do not display correctly. The reference to Line: 1 Char 1, means that the very first symbol that is probably wrong.

Is this COD??
If so back up your gamesaves from COD to a meme stick.
Then put COD in and see what happens.
If it works then the game save was corrupt.
