CiviCRM Community Forums (archive)

When I try to select a Profile to be used in the Registration page, I get a very limited selection: Name and Address, Participant Status, Shared Address, Summary Overlay, and Supporter Profile. I can see on the CiviCRM Profiles page that I have a lot more, some of which I have created, but they don't show up in the drop-down.
I tried adding "Organization Name", an existing field, to the Name and Address profile, but was rebuffed with a message saying "Cannot add or update profile field type Organization with combination of Household or Individual or Activity", which would seem to be the opposite of what I was trying to do, but never mind. Same thing happened when I tried to update Supporter Profile.
I'm trying to register participants for a Health Fair and really need the Organization Contacts profile, or at least Organization name.
Is there a switch I have set wrong somewhere, an update I need to run?
Maybe this all goes away in Civi4, but to run that, I have to update Drupal AND migrate the whole thing to a different server at my ISP  -- too much to take on at crunch time for the Fair and five other events I'm working on.
Thanks for any help.
