Auto assign usergrp during online usergroup based on ???

[leonardg]

ALTERNATIVE TO MY PREVIOUS POST.

Auto assign a new user during online registration to a usergroup based on a code user entered. Say I add a field to registration, "Code:"

If code="CLI", assign to Client usergroup
If code='EMP" assign to Employee group
etc for maybe 3 more groups.

Can anyone quote me price to do this???
