Adding counter to a user's database, when reading a post

Hi there,

I’m making a SaaS learning platform. Users can read 3 guides a day.
How would i add a counter to a users database, when they click on a guide, to track what the individuals read?

It’s a native app so it’s all elements within one page. The element that shows the guide is dynamic as well.
I’m fiddling with:
Make changes to a list of things -> Type of things: User -> List to change: Current user’s guide’s read is parent groups Guides name
I want each guide to be represented and with a counter. So if a user reads it multiple times it should just add a counter

But it’s all highlighted in red :frowning:
