Filter a galley based on a column from other list

Hello all,


I have a screen on a app where I present vehicle requests presented on a sharepoint list called "Vehicles". Then I have another list called "CheckIns" where I place the date time of check In.


I'm creating a screen where people will do check in and check out of the vehicle and what I want to do is to filter that gallery only for the requests who are blank on the checkOut column on CheckIns list.


I'm trying with look up but doesn't work:

Filter(Request, LookUp(CheckIns, IsBlank(CheckOut)) or Filter(Request, LookUp(CheckIns, CheckOut = "")


Some more hints to help visualize:

This is my Request list:


This is my CheckIns List: Request ID is a lookup column to ID from Request list



This is my gallery example:



Thanks in advance!

Hi @Miguel_MESP ,

Something like this should work - assuming these are the matching columns

Hey, not working. 

I need to do the addcolumns command? It's not possible directly through a lookup?


@Miguel_MESP ,

If you want to filter by the field - yes you need to add the column. What is not working?
