How do I send messages to different layouts in multiplayer?

I am trying to make a card game and one of the obstacles I am running into is sending a message across to a different layout.

For example, the host (player one) sets a global variable to his current card value "Player1CardValue" and wants to send it to a peer who is on a different layout, how do I send this message?

.........

Multiplayer Plugin is global. Just send message.

however Multiplayer is a large hurdle that before anyone should be using. Should first understand how C2 works. I really suggest making some simple games and getting a foundation understanging of how C2 works. Including knowing what a layout is.

Thanks the thread is solved! This helped alot! https://www.scirra.com/manual/174/multiplayer
