Hello,

i try to install some checkboxes on my map template to select layers to =
display, but it does not work.
After checking a checkbox, the layers disapear from the map and the box =
is unchecked.
=20
Here is an example html passage of may template:

...
<input type=3D"checkbox" name=3D"layer" value=3D"Gastronomie" =
[Gastronomie_check]>Gastronomie
...

And here an example passage of the mapfile:
...
LAYER
   NAME "Gastronomie"
   TYPE POINT
   DATA "Gastronomie"
   STATUS ON
   CLASSITEM "Art"
   LABELITEM "Bezeich"
   LABELMAXSCALE 2000
   CLASS=20
    NAME "Hotels"
    EXPRESSION "Hotel"
    SYMBOL "Hotel"
    LABEL
     ANTIALIAS TRUE
     TYPE TRUETYPE
     FONT "Arial"
     SIZE 10
     COLOR 0 0 0
     OUTLINECOLOR 255 255 255
     POSITION uc
   END
  END
END
...=20
