[Mapserver-users] pan/javascript

[BONNER S KARGER]

I had a similar problem, and Steve pointed me to look at the name of the main form that draws the map. In the example, it is called "mapserv" (hence the document.mapserv.zoom in the end of the script). If your form is not named "mapserv", it won't work. 

something like this should work:

<form method="GET" name="mapserv" action="[program]">

Or if you don't want to change the form name to "mapserv", change the javascript to reflect the name of your form.

Good luck,
>>Bonner
