Making a WMS layer queryable

[Jennifer Zeisloft]

Hello All-

I am attempting to serve a WMS layer that I would like to be queryable 
(using the identify feature button/Query widget from Chameleon). The layer 
appears as it should when brought into a map, but is not queryable, despite 
what it says in the layer information popup window. Other layers brought 
into the same map through other servers are queryable. I have searched the 
documentation and lists, but haven't been able to find any answers. Do I 
need to add something extra to the mapfile (layer portion is pasted below)? 
Both the context and capabilities xml files show that the layer is queryable 
(=1) and I have increased the tolerance ridiculously just to make sure a 
click hits on the point. Any suggestions would be greatly appreciated! 
Thanks in advance for your help.
