Button to File email to mail in db

I’m creating a button that has several functions. First it will check the mail in db to see if the email has already been filed if it has then exits, if not it will present a picklist for the user to select under which job ref to file it under (can be more then one) once the user selects the job refs and clicks OK the selected email should be mailed into the mail in db and marked as filed in the users mail file. I have the check working, but I cannot get the selected job refs to be appended to the subject line and emailed to the mail in db. I keep getting a type mismatch. It’s been suggested to use the Join function but Ican’t get that to work either I need some suggestions. I’ve included my button code. This button is located in the Inbox folder and must work from the view on all selected documents.
