Zoom to custom extent - PHP

[William Bronsema]

Kevin,

It sounds like $HTTP_FORM_VARS['doQuickZoom'] is not being set.

Add this:
echo '<pre>';
print_r( $HTTP_FORM_VARS );
echo '</pre>';

just before the if statement and send me the output for both an intial page
load and quickzoom page load.  This will tell us exactly what is being set
(or not set ;) ).

Regards,
Bill
