FTH - Treasurer funtion - Dues

The code is designed to figure out who is paid and who is not paid based on the selections in the invoice tracking tab.... In other words, the unpaid "follow-up" emails are supposed to go to the members selected via "SEND" (since those are the unpaid) and the paid "follow-up" emails are supposed to go to the members who are *not* selected as "SEND". The logic adjusts automatically depending on which email type you select.

I just tested the paid follow-up email case (using the button to send the email), and I do not see any issues.

Are you using the link or the button to send the follow-up email? (It actually matters.)
