Again, Steve I appreciate your extensive help. Thank you.
After removing the Contact_1 Title.Value, my concatenated fields again just show the first column. I'm going in circles and losing sanity by the hour.
I note you removed the extraneous hyperlink "junk" around the email address in the concatenated field, which is halfway there. Apparently I can't have that email address (once displayed concatenated in the combo box) be an actual clickable hyperlink? So what about a "send email" button next to the combo box. I assume I'd have to write a macro that directed that button to open an email window addressed to that specific contact. Is that a doable thing?
Some of that incorrect naming was due to my quickly stripping identifiable content but I appreciate the reminders.
The query that doesn't work in the example I posted is the ContactsQuery. It comes up empty. I assume it's because I'm struggling with getting the Site.TrialID value auto-populating in the ContactNotes.SiteID. I.e., When I create a record in the ContactNotesSubform, having it automatically assign the current Site.TrialID to that record. I know there's a way to do this, but I can't remember or come up with the right search terms.
