I think I understand where your coming from but need a little more explanation to suit my database etc....
I see how the addresses will be used by UE and how to get them in there, I just can't figure out how to assign the email addresses into the checkbox values.
I have a SQL Statement that extracts all of the records from the database that fulfils the criteria of having an email address and is a member of a department. How do I further filter the results so that I can insert the relevant user(s) from a dept into the relevant dept checkbox?
Sorry - I guess this isn't so much of a UE question now.
