You'll need to set up a relationship that links your table of email templates to your table of contacts.
Contacts::SelectedSubject = EmailTemplates::Subject
Format SelectedSubject with your value list of subjects from EmailTemplates
You can then use an auto-enter field option to look up (copy) the email body from templates into a text field in Contacts so that you can use it as the starting point for your email.
That worked!!! Thanks! I had too many relationships and only needed the one: Contacts::SelectedSubject = EmailTemplates::Subject
