Count Related Formula Help.

[dodom2]

Hey guys. I'm having the hardest time counting some related records.

So I have an entity called reservations. This reservation has many to many related fields to another entity called "reservation items". These items are player spots for our laser tag arena. So if a person were to make a reservation for 6 players then we would relate to 6 records in the reservation item entity. I need to count how many records are related to each reservation record.

My relationship setup: https://prnt.sc/11jv2am

My formula:

totalReservationItems = entity\countRelated(reservationItems,);

My issue:

When I save I get an error 500 and of course, refuse to save the record. I check the log and see this entry:

You forgot to put the string questions:

totalReservationItems = entity\countRelated('reservationItems');
