I have successfully implemented a MultiValue control on a form and it seems to work in both Team Explorer and Team Web Access. However, I have a set of users who will be working exclusively with the SharePoint portal site. When I bring up the form there, I see an error in the field box.

Is there a way to get the multivalue control to work in the SharePoint ui?

This is not a scenario that I've come across but I guess that the implementation will be different in SP. I will take a look and come back with my findings.
