Hey, weblink! click in the field and choose Replace from the Records menu. Use with CAUTION. Make a backup first, perhaps?
you have a choice of replacing with a calculation, so select that and enter "" (to clear the field). This works only on the found set, so if you want to clear all records, Show All first.
Again, use with CAUTION!
Thank you very much! I wasn't looking for "replace". Perfect solution!
