This is a total long shot, but here goes.
My (old) responsive form has a single line text box where the name of 'the person making the complaint' needs to be entered. These are not people internal to our company, so I can't use a 'people field' here. The group wants to enforce a "Last name, First name" format, but does not want to have a seperate field for inputting a Last Name and a First Name (go figure!). I've pretty much told them I cannot enforce that type of formatting (to get myself off the hook), but figured I would throw it out here and see if anyone has suggestions.
Note: I can not use any custom coding, so I'm hoping for solutions either using RegEx or rules, etc.
(Don't you hate it when someone wants something but they are not willing to work with you to get it??)
