I am trying to connect zapier to mailerlite.
I have a zap set up so that when a person signs up for a particular course (let’s call it digital party planner) they get added to a group in mailerlite (let’s call it zenler-digital party planner). However, when I set it up, I didn't put anything in the choose value section on zapier because I want it to choose the group based off the course in zenler. It therefore failed and said the group value was 0 and needed a number. How do I do it so that it picks the correct group in mailerlite based on the correct course in zenler?
