Newbie and javascript problems

[Luis Treviño]

Ian:

Remember to write the imgxy value (hidden variable on your template) with
the resulting x,y values obtained on your pan function. something like:

function pan(direction) {
   var x, y;
   if(direction == 'n') {
     x = (400-1)/2.0;
     y = 0 - (300 * pansize)/2.0;
....etc
  document.mapserv.imgxy.value = x + " " + y;
  document.mapserv.submit();
}
it should work. Hope it helps

Regards
Luis
