Do you get as part of the error message, record #? This would be the actual record number of the form .scx file (table). You can manually open the form as a table (use myform.scx) go to that record and make a manual change (make a backup copy of the form first). You can also browse and look in the methods field for all the records to try to correct the problem from there.
