[Solved] How can i make this variable be changed for the entire script?

Tittle says it all. Here's the script:

Script:

game.ReplicatedStorage.HLC_CTRLS.W_Began.OnServerInvoke = function(player)
    W_KeyDown = true
    print("Remote function was invoked")
end

if(W_KeyDown)then
    print("Variable was changed.")

end

The first function prints, but the second doesn't. How can i make it be changed for the entire script?
