Fellow monks,

I'm having a bit of a problem finding any docs on this. I want to set the default on a radio button. This is my code thusfar: 

$shape="square";

(stuff deleted)

foreach ('square  ', 'circle ', 'polygon'){
         $frame2->Radiobutton(
                              -bg=>COLOR,
                              -activebackground=>COLOR,
                              -text=>$_,
                              -font=>'code14',
                              -value=>$_,
                              -variable=>\$shape,
                              )->pack(-anchor=>'w');
         }

My question is: Why isn't the radio button being set to square initiallly since I've set the variable? The radio buttons are being drawn fine, but with none selected.

All I can find in Mastering Perl/Tk is a reference to the default on a regular button. There is nothing listed in the reference charts in the back either. Have I missed something here?

Thanks!
