Hi Stefanos,
When I try this locally with CGI, I also get the same value on first
load for [mapx] and [mapy] of -1.0000,-1.0000 likely because there is no
point click yet. But when I do click, the values for [mapx] and [mapy]
returned look valid.
You might also want to check the returned values for [maplat] [maplon]
as well.
If it is related to a projection issue, you might want to check the
mailing list archives for relevant discussions, such as
http://osgeo-org.1560.x6.nabble.com/retrieve-map-coordinates-with-different-EPSG-td5000369.html
I am testing with MS4W 3.1.3 (MapServer 7.0.1).

Hello list.
I'm having a problem I can't understand where it's coming from. I'm
using [mapx] and [mapy] parameters to get the coordinates of a simple
click. When I click anywhere on the image, the resulting x,y is at least
1 kilometer North-West from where it should. The image coordinates look
correct but the x,y are really wrong. I'm copying and pasting my form
variables below:
<form name="the_form" method=GET action="/cgi-bin/mapserv">
<input type="hidden" name="imgext"
value="[mapext]">
<input type="hidden" name="map" value="[map]">
<input type="image" name="img" src="[img]"
width="700" height="500">
<input type="hidden" name="zoomsize" value="2">
When I first load the map with the following URL
http://127.0.0.1/cgi-bin/mapserv?map=/home/stefanos/mapdata/mymap.map
<http://127.0.0.1/cgi-bin/mapserv?map=/home/stefanos/mapdata/trikala.map>
x, y are set automatically in -1,000000 -1,000000.
Any idea?
Regards,
Stefanos
