The controlsource is something else. The reason I store this.value to thisform.myProperty is so I can do a check for the number of lines entered in the edit box. I do this check in the interactivechange() of the editbox. If the line number exceeds myMaxLineNumber then I notify the user and set this.value=thisform.myProperty and this.refresh

I have tried commenting out every thing from the interactivechange() except

thisform.myProperty=this.value

Is there maybe a different way of doing what I want to do?
