Why won't anything happen when i click the button?

So I was experimenting with remoteEvents, and I was trying to make it so everytime the player clicks the button, he gets one point. But I get multiple errors doing so. Here is my local script

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local remoteEvent = ReplicatedStorage:WaitForChild("RemoteEvenTest")
    local plr = game.Players:GetPlayerFromCharacter(script.Parent.Parent)
    plr.leaderstats.Kills.Value = plr.leaderstats.Kills.Value + 1

remoteEvent:FireServer()

and here is my serverscript

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local remoteEvent = ReplicatedStorage:WaitForChild("RemoteEvenTest")
function hi()
    game.Workspace.d.BrickColor = BrickColor.new("Lavender")

end
function die()
    remoteEvent.OnServerEvent:Connect(hi)
end
script.Parent.dd.MouseClick:Connect(die)

Sorry for my weird variables, but what have i dont wrong?
