[Geomoose-users] Identify tool

[Jeffrey Schmitz]

Thanks for the help!

I did add the suggested line to the metadata section, and verified
that the projection and table were correct... still isn't working.
I realized I never posted the actual error windows that pop up. They read:

"Unhanded request Return Internal Server Error" quickly followed by
"Invalid Response"

anything else I could possibly be missing? I can't seem to find anything...
