Something to remember with the Excel Spreadsheet ABS Calculator,
you need to "enable macros" for it to work correctly. When you
open the document you should have the option to "Enable Macros"
somewhere within the MS Excel tool bar (sometimes a pop-up box).
If you don't enable macros the calculator won't work correctly.
It really is beneficial to play with it and learn how to
manipulate the figures. If at first you don't succeed, just keep
trying and ask for specific help, i.e. I put the number 16 in box
D32 and nothing happened.<br>
