Hi!
I would like that when I click on a row in the table above, then in the table below, the details will be shown to me in the sub-collection. It doesn't work and it doesn't recognize the data source..
I am an intern student, please help me guys 
Hey @stavco28!
Is this still something you're looking into?
A common debugging step is to check whether or not the query runs properly if you hardcode in the uid instead of passing it dynamically from the table. Were you able to get the query working before connecting it?
It might also help if you could post a screenshot of the query results!
