Blocking Data Entry
As I have previously commented, Filemaker is very new to me - although
database programming is not a mystery.
What I would like to do, is to block the entry of data into a field, unless
another field - flagged - has a positive entry. Even better, would be to
mask this field unless the flagged field said "Yes".
Can I do this? I know how to do it in Pascal, but how about in Filemaker?
