Zoom to custom extent - PHP - SOLVED

[Kevin Grootendorst]

Bill,
Finally, I was able to get my application working properly.
After I changed $HTTP_FORM_VARS to $http_form_vars, I moved the code in my
app.php file closer to the top of the file.
The application works perfectly.
Thanks for all your help and your php tips, it's greatly appreciated.

Regards,

Kevin
