Excell I need to overlay a scanned form and an excel grid to type the info in the correct boxes. The space limitations are tight. I would then like to print both overlays as one landscape A4 document. Anyone any ideas? All suggestions gratefully welcomed. Thanks.

Excel 2007 is limited to 2 Gigabytes of memory for the Excel process under Windows XP/Vista (Windows memory limit).
This 2 Gigabyte limit is a limit on the Virtual Memory address space. Virtual memory used by a process is larger than the working set memory reported by Windows Task Manager, so the amount of useable memory under Excel 2007 is considerably less than twice that of Excel 2003.
Because Excel 2007 (Excel12) also requires more memory to store the indexes to the increased number of rows and columns you may not be able to load larger workbooks under Excel 2007 than was possible under Excel 2003. Memory Fragmentation may also mean that it is difficult to make use of all of the available 2 GB of virtual memory.

Many of the individual memory limits listed below have been removed in Excel 2007.

Excel 2010 is available in 2 versions: 32-bit (2 Gigabytes of virtual memory) and 64-bit (8-Terabytes (which is 8000 Gigabytes of virtual memory)).
The 32-bit version has the same memory limits as Excel 2007, but the 64-bit version, when used with a 64-bit Windows operating system, will have extremely large memory limits.
Note that the different versions of Windows Vista 64-bit and Windows 7 64-bit support differing amounts of RAM.

1. Click the Microsoft Office Button, and then click Excel Options.
2. Click the Customize category, select All Commands in the Choose commands from list, select Option Button (form control), and then click OK.

1. In Excel 2003 and in earlier versions of Excel, click Option Button on the Forms toolbar, and then draw the outline of the button on the sheet.
   
   In Excel 2007, click Option Button (form control) on the Quick Access Toolbar, and then draw the outline of the button on the sheet.
2. Select any cell in the worksheet.
3. In versions of Excel that are for Microsoft Windows, right-click the option button, and then click Assign Macro.
   
   In versions of Excel that are for Macintosh, press COMMAND while you click or press CTRL while you click, depending on your operating system version. Then, click Assign Macro.
4. In the Assign Macro dialog box, click the name of the macro that you want to assign to the option button, and then click OK.

1. Click the Microsoft Office Button , click Excel Options, and then click the Formulas category.
2. In the Calculation options section, select the Enable iterative calculation check box.
3. To set the maximum number of times that Excel will recalculate, type the number of iterations in the Maximum Iterations box. The higher the number of iterations, the more time that Excel needs to calculate a worksheet.
4. To set the maximum amount of change you will accept between calculation results, type the amount in the Maximum Change box. The smaller the number, the more accurate the result and the more time that Excel needs to calculate a worksheet.
