Change Focus to Group

[Jeff Honken]

I'm trying to switch the focus from a field that I'm in to a group of
radio buttons by entering "Return".  I'm using the following:

on returnInField
 focus on group ProviderRadio
end returnInField

The focus seems to be working great from field to field but when I try
to go to a group it errors.  Can someone steer me in the correct
direction on this.  Jeff
