Updateable baq linked in dashboard

I’m trying to create a dashboard in application studio that will show all customers that have been added or changed based on a date parameter. The top grid shows those customers.

Where I’m having the issue is I want to be able to select a customer from the top grid and then just see that information in the bottom grid

The top grid is based on a date parameter BAQ and the bottom grid is based on an updateable BAQ as I want to be able to make corrections to the bottom grid if we find errors.

If we take off the parameter on the top and the updateable on the bottom, we can get this to work.

How can I get this to work with the parameter & updateable BAQs?
