I think your outer logic is fine, but it's failing because inside
GetFieldData() nofield is set if the text buffer or the field is
missing - these shouldn't happen if your code is written
correctly. What you want is to have that flag set if your
field is *empty*. Change GetFieldData so that the
if (FldGetTextLength (pField))
that does the copy has an else that sets nofield to true.
Your outer logic then has more chance of doing something
useful.
