No can do. When you specify a DE class to use for a form, you can not add anything to the DE while in the Form Designer. You have to add/modify/etc., the DE in the class designer. Then whatever changes you make there will show up the next time you open up the DE in the form designer. I have already had this discussion with some on the VFP Dev Team in a previous thread here or on a MS Newsgroup.
