refreshing Page on change in popupmenu

[nappaji]

Hi,
I have a statement like below in a CGI script:
@reporttypes = ('ABC','XYZ','RST');
print $query->popup_menu( -name=>'pmReporttypes',
-values => \@reporttypes);

If I want the page to refresh when I change the selection in the popup menu, how do i do it???

Is there a syntax like,????
print $query->popup_menu( -name=>'pmReporttypes',
-values => \@reporttypes,
-onChange=> 'refresh');

This doesnot work, but is there something like this.
