Stopping repetitive jumps in a Server Script?

So, You might be wondering "Why are you trying to make something localsided on a serverscript?" Well the reason is values, I have to modify a value with a serverscript so everything else works.

Everything works as intended, But the script gets played three times simultaneously and I just want it to play once each time the player jumps.

Here's the script.

local Players = game:GetService("Players")
local LP = game.Players:GetPlayerFromCharacter(script.Parent)

local Stat = LP:FindFirstChild("Statistics")
local Stamina = Stat:FindFirstChild("Stamina")

local debounce = false

LP.Character.Humanoid:GetPropertyChangedSignal("Jump"):Connect(function()

    local Jumped = LP.Character.Humanoid.Jump

    if Jumped == true then
        if debounce == false then
            warn(LP.Name)
            debounce = true
            if Stamina.Value <= 0 then
                Stamina.Value = 0
            else
                Stamina.Value = Stamina.Value - 1
            end
        end
    end
    if Jumped == false then
        if debounce == true then
            debounce = false
        end
    end

end)
