$note->append_page($obj, $LABEL) ?





When I try to append page to Notebook and pass a LABEL I'm getting error ?
$note->append_page($obj, $LABEL) 
the error is :
Mon May 13 19:06:40 2002 Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkWidget' at 
lib/Gtk/PropWindow.pm line 42

any idea why this happen ? I tried with single, double quoted string and variable !!
