[mapserver-users] What's wrong with this string?

[Azimuth, Erwin Perik]

Lyndon,

i do not know what your defaults are, but check to see if something like 
following is used:

<input type="hidden" name="imgext" value="[mapext]">

Think you are missing the image x and y to use for the zoom.

Use something like this to also pass the zoom value:

<form method="GET" action="/cgi-bin/mapserv">
   <input type="hidden" name="map" value="yourmapfile">
   <input type="hidden" name="imgext"  value=="[mapext]">
   <input type="image" name="img" src="[img]" border="0">
   <select name="zoom" size="1">
       <option value="2" selected> Zoom in 2 times </option>
       <option value="1" > Recenter Map (PAN) </option>
       <option value="-2" > Zoom out 2 times </option>
   </select>
</form>

(BTW, negative coords are not the problem)

Erwin
