When performing a caluculation... ALL fields within a calculation must have
the option to "calculate on exit" selected (not just the field that holds the
calculation).

How do you enter a calculation within a table in a form template? I am

I have tried everything within the help menu.
I am using WORD 2002 and have Windows 2000 Professional.
