Hi Ted,
Thanks for the response back. It's a 'view' within the InfoPath form itself, sorry for not clarifying.
I'm just not quite sure how to link a sharepoint group to the editable view in the form. I was thinking about cross-checking the current user account with a sharepoint list which has a column in it with a defined allowed list of user account who can update the view on the form, but I wasn't sure how to go about doing that either!
Thanks,
Jason.
