[mapserver-users] Problem with Variable Substitution for EXPRESSION

[Lime, Steve D (DNR)]

I'm going to try a copy of the mapfile here and see what happens... Will report back later today.

Hello,

If I was in your situation, I would follow Steve's advice and test it 
through the commandline (mapserv -nh QUERY_STRING="blah") to test your 
request in normal CGI mode.

Then if all else fails, create a very small one layer mapfile with a 
tiny data file and package that with a requests.txt file, and submit 
that to the MapServer Issue Tracker, or event point to it here on the list.
