Click to punch animation only works once but when you click again it doesn't?

So basically this is a Click to punch script. Every time you hit something that means that it does damage to thing its touching. But for some reason when you click one time it works perfectly fine but if you try do it again it doesn't. Here is the code Normal Script

local debounce = true



local function onServer(player,ID)

if debounce then

debounce = false

local character = game.Workspace:FindFirstChild(player.Name)

local humanoid = character.Humanoid

local punchAnimation = script.Punch:Clone()

punchAnimation.AnimationId = "https://roblox.com/asset/?id="..ID

local playerAnim = humanoid:LoadAnimation(punchAnimation)

playerAnim:Play()

wait(3)

debounce = true

end

end



game.ReplicatedStorage.AnimationEvents.Combo.OnServerEvent:Connect(onServer)

This is the damage script inside the Normal Script

local DamageValue = script.PunchDamage

DamageValue.Value = math.random(5,7)



local function touched(hit)

if hit.Parent:IsA("Model") then

local char = hit.Parent

local hum = char.Humanoid

if hum and char.Name ~= script.Parent.Parent.Name then

hum.Health = hum.Health - DamageValue.Value

script.Disabled = true

wait(.5)

script.Disabled = false

end

end

end



script.Parent.Touched:Connect(touched)

Local Script

local player = game.Players.LocalPlayer

local mouse = player:GetMouse()



local function buttonDown()

if player then

game.ReplicatedStorage.AnimationEvents.Combo:FireServer(02970353895)

end

end



mouse.Button1Down:Connect(buttonDown)
