# Multiplayer Replication Unreal Engine 4

I have variable=count(integer) in a Character Blueprint.
I want to increment the variable when user presses the 'R' key.
What do I so in the Blueprint that variable remains the synchronized between the server & client?
For example:
In server- 'R' key pressed 3 times so count value should be 3.
In client-'R' key pressed 4 times, so then the value should be 7.
