I'm not sure why it is doing it...it don't generally use the FOR clause of REPORT FORM, and you are changing the value of the field on the fly.

I would be more inclined to do the REPLACE at the end of the report (for example, add a group on eof(), and put your UDF call there). That way it is an all or nothing deal...if user cancels the report.

select owrk
replace flagged with "P" for flagged == "R"

>>Hmmm...if you disable the call to the UDF (regarding wExist()), does it print properly?
