Conditional Formatting on Two Different Collections Using ForAll/Patch

[jpmarcy]

Hello - I am trying to change the color of a label in one gallery to green after it finds a match in another gallery (all matches). In the screenshot below, you can see how this app works. The top button gallery acts as a filtering mechanism for the 2 galleries beneath. The bottom left gallery has its own collection, the bottom right gallery has its own collection, and the buttons above filter the galleries based on the team name.

Currently, only one of the Approved Games list games is recognized as a match even if there clearly multiple matches. I'm guessing I need to setup a loop to record multiple matches in the Sponsored Games collection after each button is selected, but I can't seem to figure that out. I have a match boolean column ready to go in the Sponsored Games collection; I just need to figure out the loop/patch formula.

Any guidance would be much appreciated. Thanks!

Here is the ForAll loop I cannot get working due to "Invalid Argument type" on the = operator.

ForAll(colApprovedGames,
        If(
          colApprovedGames.Game=colSponsoredGames.Display,
            Patch(colSponsoredGames,
              Defaults(colSponsoredGames),
              {Match:true})
          )   
 )

This ended up working for me. On the Color property of the Sponsored Games label: 

If(lbl_SponsoredGame.Text in Gal_ApprovedGames.AllItems.Game,Green,Red)
