Hey, thanks for the reply, Chan.
I've attached the source code for my html template. In it you can see the
recommended/necessary changes for implementing the mapplet:
1. named the FORM that is sent to the mapserver app.
This is the same name that's refered to in the mapplet_apply function.
2. added the mapplet_apply and mapplet_error functions
3. added the hidden variables: imgxy and imgbox
4. replaced the output map image (<img src= ...>) with the applet
definition (<applet codebase=......>)
Also, here's another link to my mapserver site:
http://geneva.geoplan.ufl.edu/download/mapserv/htmltemplates/doqq_init.html
I hope that this one will work for you. Please let me know if it does or doesn't work.
Oh and just to reiterate, I'm getting the following error message when I try
to drag zoom on the applet map image:
Applet mapplet document.mapserv has no properties
which of course is referring to my FORM, "mapserv".
Thanks a bunch,
Christine
