jump to slide using variables and timelines

Hello, I am creating a matching cards game and wanted to show a slide when the correct combination is picked, and then return to the game to carry on selecting combinations.  

The trigger to “jump to slide X, when Timeline Ends, IF [variable] = True” works okay, but when I return to the Game slide it keeps jumping back to slide X when the timeline ends (Timeline is set to 2.5 seconds).

I have tried adding a T/F variable to slide X to = True when user clicks a certain button (to return to the game) and then added this as a second condition to the initial jump to slide trigger (“jump to slide X, when Timeline Ends, IF [variable] = True AND [variable 2] = False”), but this then stops the trigger from working at all.

Am I trying to do something that is not possible?

Any help would be appreciated!
