Roll-Up Calculations

Hello - I have set-up the roll-up fields exactly the way the video shows and when I go check the festival it lists the number of VIP and General Admission tickets sold as zero. I have double checked that the attendees record is marked VIP or General Admission as well. Why isn't it showing the number of ticket type sold correctly by festival?

This is what my "VIP Tickets Sold" RollUp field definition screen looks like.

You'll need a similar one for the General Admission calculation but the Field Criteria Value at the bottom should read "General Admission" instead of "VIP"
