I'm doing an "on load" statement to run a global DN Query against a custom
effective-class of objects representing "schools"

I ask for the Pick List to display a three letter acronym (ccpsSA) and what
I get back in the pick list on the form is the three letter acronym PLUS
"OU"

So If the school is PVE, I see PVEOU...

Any idea where I might most likely find the problem?

Here's my "onload" action
IDVault.globalQuery("ccpsSA", "schoolTLA")
