Hi! So here's your form back with some changes - hopefully some of them are right, since I'm guessing a bit. On the Form Load & the Course Code field, I have added rules to query for the right course code for the data connection that the Quotas section is bound to. Since we are only querying for those that match on course code (based on what your data connections look like - I'm not sure if your lists actually match), you should only get back the row(s) that match. Then, I added another rule to populate the student quotas available field.... I moved that field out of the secondary data source repeating section, however. And if your secondary data source may return more than one row for each selected course code, you'll want to change the formula to sum each field from the 2DS prior to adding them up.
