>>I have the 'this.formset' reference, which it does not like. Seems like I have had the same problem in the past .. where a this.form does not work so i change it to this.parent.parent. If the control or method is anywhere under the form, should this.form work?

To see what is really happening, open the debugger and enter _screen or _screen.activeform in the watch window. You can click on the plus signs to find what you need. Once you locate the object you want, you can drag it to the command window and it will expand the syntax for you.
