So my animation keeps looping when I click the button to punch, why is this?

I'm not the best at scripting but I thought that I had gotten the hang of the basics and yet now I for some reason am unable to fix this. This is code for punching for my game. Here is the code:

local Tool = script.Parent
local Player = game.Players.LocalPlayer
local Char = game.Workspace:WaitForChild(Player.Name)
local Humanoid = Char:WaitForChild("Humanoid")
local Check = 0
local Enable = true
local idle = script.Idle

Tool.Equipped:Connect(function()
    local idleey = Humanoid:LoadAnimation(idle)
    idleey:Play()
    Tool.Unequipped:Connect(function()
        idleey:Stop()
    end)
end)

Tool.Activated:Connect(function()
local humanoid = script.Parent.Parent:WaitForChild("Humanoid")
if Enable == true then
    Enable = false
    if Check == 0 then
        humanoid:LoadAnimation(script.Anim01):Play()
        script.Parent.Combo.C0:FireServer(Char:FindFirstChild("LeftHand"))
        script.Swing:Play()
        wait(0.4)
        Check = 1
        Enable = true
        Humanoid:LoadAnimation(script.Anim01):Stop()
    else if Check == 1 then
        humanoid:LoadAnimation(script.Anim02):Play()
        script.Parent.Combo.C1:FireServer(Char:FindFirstChild("RightHand"))
        script.Swing:Play()
        wait(0.4)
        Check = 0
        Enable = true
        Humanoid:LoadAnimation(script.Anim02):Stop()
    end
    end
 end
end)

while wait(3) do
    if Check == 1 then
        Check = 0
    end
end

all help is appreciated.
