I am trying to do a formula in a table in Word. (What's the deal with MS
not using classical logic, as in VB -- it's so easy there, but so difficult
in Word/Excel!!!?)

Here's what I tried, unsuccessfully, where ff1 is a bookmark representing
the value of a form field within a table:
=IF((100-ff1=0) "" (100-ff1))

I have tried various machinations of this, to no avail. Please help me,
someone.....

TIA
