Need formula for excel

Try using "count if blank"
I am assuming that you need the value to be on sheet 3
If you want the value to be on another sheet, it is more complicated, you will have to "paste special" the value to a different sheet.

Below is the formula for "2". The logic should be obvious from this so you can adapt for "1" or a combination of 1 and 2. This need to be written as one long formula so I have pasted it in to this reply so you can do a copy and paste into your spreadsheet. Sorry its not very readable in this form but you could paste into word so you can break it down and examine structure.

=IF(OR((AND(Sheet3!A12="WA",OR(Sheet3!AH2="Lewis",Sheet3!AH2="Pacific",Sheet3!AH2="Wahkiakum"))),(AND(Sheet3!A12="OR",OR(Sheet3!AH2="Clackmas",Sheet3!AH2="Multnomah",Sheet3!AH2="Washington")))),"X"," ")

The crude solution is:
=IF(Sheet3!I2="WA",IF(Sheet3!H2="Vancouver","X",IF(Sheet3!H2="Camas","X",IF(Sheet3!H2="Ridgefield","X",IF(Sheet3!H2="Washougal","X",IF(Sheet3!H2="Stevenson","X",IF(Sheet3!H2="Hockinson","X","?City?")))))),"?State?")

Where ?City? appears when the city referenced in H2 is not part of the lookup
and ?State? appears when something other than WA appears in I2.

But there is probably a better way to do this using an array of valid values like the one below:

AL NY TX WA Birmingham Albany Abilene Camas Huntsville Buffalo Galvaston Hockinson Russell New York Houston Ridgefield Stevenson Vancouver Washougal

In the scenario you could stuff the array in another worksheet and use the HLookup function to find the "Sheet3!I2" value in the first row of this array to determine which column to look in, then VLookup "Sheet3!H2" in the column of that array to see if the city referenced exists. Of course this is a much more complex formula, but it would be easily extendible without changing the formula every time.

For mor info, see "Lookup and Reference Functions" in the Excel Help.

With data in A1 to C1: A2 =IF(A1>0,1,0) B2 =IF(B1>0,1,0) C2 =IF(C1>0,1,0) A3 =SUM(A2:C2)

You need to change the =IF(AND to =IF(OR
Using AND is saying both conditions must be true. Using OR is saying either condition 1 or 2 need to be true

Use the IF and Date functions together. On sheet 3, put the birthday (3/15/1954) in cell B1, put the beginning date (1/1/1946) in cell C1 and the ending date (12/31/1964) in cell D1.
Then on Sheet 1, but the following formula in the cell you want an X to be placed in.
=IF(AND(Sheet3!B1>=Sheet3!C1,(Sheet3!B1<=Sheet3!D1)),"X"," ").
Make sure you type the formula Exactly as it appears.

You can use this formula
=IF(A2<=100,"Within budget","Over budget")
Which means
If the number above is less than or equal to 100, then the formula displays "Within budget". Otherwise, the function displays "Over budget" (Within budget)
or you and try something like this
=IF(A2=100,SUM(B5:B15),"")
which means
If the number above is 100, then the range B5:B15 is calculated. Otherwise, empty text ("") is returned ()
I got these examples from the help within Exel they give several more examples and more expaination.

formula for the keys or short curt for excel

Nope, sorry, although I am truly an expert at Excel formulas, I do not understand what you are trying to end up with in the final cell. We can compare a specified field with two spreadsheets - use named ranges and index/match lookup formulas. But then where you really lose me is in reading "a generic field" to find a match, and then placing what "data from another field" into what "other sheet" - ? See the confusion?

Best way to compare 2 given parameters would be to use a nested if formula, with index/match combo. Here is a simple Excel example of how such a formula could be structured:

Sample Data (columnar arangement):
A1: Part B1: Code C1: Price D1: Find Part E1: Find Code
A2: x B2: 11 C2: 5.00 D2: y E2: 12
A3: x B3: 12 C3: 6.00 D3: y E3: 11
A4: y B4: 11 C4: 7.00 D4: x E4: 12
A5: y B5: 12 C5: 8.00 D5: x E5: 11

To retrieve the price for part y with code 12 and return the value to cell F2, type the following formula in cell F2:
=INDEX($C$2:$C$5,MATCH(D2,IF($B$2:$B$5=E2,$A$2:$A$5),0))

Press CTRL+SHIFT+ENTER to enter the formula as an array formula. The formula returns the value 8.00.

To take this one step further, with range names, this example will find one value at a specified location which matches a specific row header value and column header value. Let's say the range is home values (Range=HomeVal), Column A of HomeVal contains street addresses,"row headers" (Range=StAddress), and Row 1 contains dates of the various values that are in the body of the table, "column headers" (Range=Dates). To return the specific value from the range HomeVal to another sheet, where A1=address specified and A2=date specified:
=INDEX(HomeVal,(MATCH($A$1,StAddress,0)),(MATCH($A$2,Dates,0)))

Then make sure to press CTRL+SHIFT+ENTER to enter the formula as an array formula - if you only hit enter, these types of formulas will not work properly.

Please post back if you need further help, with more details, otherwise thank you for using and rating FixYa!

Try this:

=IF((E2<38),B2*14.3, IF((E2<44),B2*15.05, IF((E2<50),B2*15.8,0)))

Note that <38 is the same as <=37. Also, you can replace the 0 at the end with empty quotes "" for a blank cell.
