I added the script and the button control but I am not sure about the third item you mentioned. I added the lines "<input type="hidden" name="imgxy" value="[center]" /> <input type="hidden" name="zoom" value="2" />" in the mapserver variables section but when I click the button nothing happens? What is the problem?
