Answered Assign a user to a group based on a dropdown value selected during registration?

I'm using the Login package. I would like to supply the registrant with the option to choose their group during registration.

I have the form working and adding the user, but I can't figure out how to vet the value of a dropdown into the &usergroups=`` statement in the [[!Register]] call.

It's probably so simple I'm going to feel like an idiot after someone tells me. >.<
