He is trying to get the groupbox title,i.e. Marital Status in this case.
HI Marc, Is your groupbox title going to be dynamic every time? why dont you create a groupbox and name it Marital Status in design time.
I don't have system access right now but you can try to copy the text property of groupbox into a local javascript variable and see if it gets the title of the groupbox.
Thanks,
