Hello Admins!

I need help! I am applying for a job and they have asked me to present a bunch of solutions for a make believe Nonprofit company. I got through 90% of it but I am stumped on one problem.

How can I show the Number of Classes (Sessions) a Mentor is teaching on their contact record?

So I loaded a playground with NPSP and PMM and Ive created the programs, the services offered and the Sessions that are scheduled.

I loaded the mentor as the " Service provider" on the Scheduled service, how do I connect them back to the mentors contact record?

I thought I could do a roll-up field but I couldn't figure it out.

Please let me know what you suggest?

Thanks everyone!!!
