Queries

[Peter Kingsbury]

Hello Pericles and List,

I have gone over the provided attachments... they are certainly helpful. 
Many thanks!

One problem I am having, is that Chameleon does not seem to take into 
account the HEADER/FOOTER/TEMPLATE fields I place in the mapfile 
layers... it simply takes from the QueryResults.phtml file that comes 
with the server.

I've confirmed that the placement of the HEADER/FOOTER/TEMPLATE fields 
-do- help, as without them, I get empty query results each time.

Each time that the query results appear with the QueryResults.phtml file 
as a template, I get a table with the complete data set, which is good, 
but a little too much information for my purposes! The mapfile seems to 
ignore my custom .html templates.

Any ideas?

The search continues,
- Peter
