What Larry and Cindy told you is correct, but they also neglected to tell you that the way you are trying to do this is the wrong way to go in VFP. You're working too hard. While SCATTER and GATHER might have been the way to do homegrown buffering in FP 2.x, in VFP, we have real buffering, and you can save or roll back changes with TABLEUPDATE() and TABLEREVERT(). So you can bind your controls directly to fields in a table or view. Look these up in the documentation, and also look at GETFLDSTATE(), GETNEXTMODIFIED(), CURVAL(), and OLDVAL().
