mrt table showing wrong record number

There were two issues I had to correct to get this working:

1) You had a redirect in your Update server behavior, so the MRT code never ran. The record in your screen shot was old and leftover from your previous testing I'm assuming. It wasn't being inserted by the update page. I removed the redirect in the update server behavior.

2) It looks like you had recreated the checkbox and repeated region after applying the MRT server behavior. The server behavior adds code to the repeated checkbox that wasn't there. I had to re-apply the MRT server behavior to get it re-added.

Once doing those two things the page started working properly.
