Template example (but other demo on the web are still very useful for
basic commands):
I have a div which must contain something created by Mapserver, so I use
a particular CGI variable and Mapserver constructs that element (the
legend, the reference map, ...) Use square brackets [ ] for defining the
cgi-variables.
<div>
[cgi-variable]
</div>
or if you want to view the actual scale
<input name="scale" value="[scale]" />
Mapserver itself puts the real actual scale value in the value attribute
of the input.
Hope this helps
Bye, Carlo
