I want it to be a dynamic page, so that request is not sent yet. And when XXX is checked

<input type="radio" name="rad_server_type" value="xml">XXX;
<input type="radio" name="rad_server_type" value="org">YYY;
[download]

then this should be shown:

 print $q->popup_menu(-name=>'xml_server',-values=> \@array_of_selecti
+ons);
[download]

otherwise not. Something like "on....event" javascript
