Client to server RPC

i have a listen server and 2 clients , each client has a button , and i have an integer value in the level blueprint , i want when i press the button at the client the integer value in the level blueprint at the server to be increased and not the value in the level blueprint of the client , is this possible ?

The only solution was to use event tick in the level blueprint , so that the server always binds the event dispatchers of all pawn classes of the clients to a certain event which would then be able to run on the server
