How do I have a global lives and then use that for multiple level/layouts?

Hi, how do I have global lives set for the player, then use that for my player lives(hearts) when used at different layouts?

Right now the Player lives are set in the Player's variables. However it is not working on Layout2, but it works in Layout 1.

Instead of player instance variable use a global variable for lives, that is more common and it is global for all layouts.

Thanks
