[Cartoweb-users] Zoom tools do not make anything

Hello,
First, your problem is due to incoherence between the scales defined in
location.ini and the scale given to cartoweb by mapscript (mapserver).
If you add "{t}Current scale:{/t} 1:{$currentScale}" to your template
you'll note that given scale is incorrects, it doesn't correspond to
those defined in the location.ini
On first load, the scale is lower than the minscale so user cannot zoomin.
Having a try with similar datasets and extents, I got it working using
"UNITS DD" in the mapfile (MAP object). (Your extent values are given in
DD). With this Mapserver gives a more comprehensive scale and then
Cartoweb is able to manage the scale list.
You should try it.
Second possibility is to project your map in a cartesian system with
meter units for your map and its extent.
Regards
Pierre
