Thanks Kevin

I understand that the control ID is assigned by a wizard. That means a particular field of a particular table that appear in more than one form, will have different control ID. Is there a way the the control ID of a field by default takes the form of "tablename_fieldname". This would ensure one field in one table can have only one control ID in all the forms that the field appear. In this case, it will be easier for my report engine to call a function by passing the table name and field name.
