I am trying to do a comparison between an original workbook with a workbook
created from the original which has had changes made to it. I used the help
file to add this button to the quick access toolbar. However, I can not make
the button work. I have the workbook open as I was told do in the help menu
but the button is "greyed" out (the way options normally appear on drop down
menus when you can't use a feature for whatever reason). Any suggestions??
