Sending parameter to level BP

Hello,

My question is quite simple, how to pass an integer value to a level blueprint? I use HUD buttons to change the integer value. When integer changes the HUD also changes to another type, but I would like to change the pawn as well. Please see the attached picture.

Is there a simple way to cast this integer to the level blueprint?

Thanks!

can anyone answer to this question? This issue is stll open to me.

Thanks!
