Crouching script will not work properly. Could somebody help?

So, I am making a crouching script but when you press the E key, it plays but it will not stop playing. I have the animation type set to action, and the animation is looped. I know that the reason why it's not working is because it's looping, but I want it to stop when the player takes their finger off the E key. I did not get any errors. Here's my code.

local userinputservice = game:GetService("UserInputService")
local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
local animation = script:WaitForChild("Animation")
local dance = humanoid:LoadAnimation(animation)
userinputservice.InputBegan:Connect(function(input,process)
    local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
    local animation = script.Animation
    local dance = humanoid:LoadAnimation(animation)
    if input.KeyCode == Enum.KeyCode.E then
        dance:Play()
    end
end)
userinputservice.InputEnded:Connect(function(input,process)
    if input.KeyCode == Enum.KeyCode.E then
        print('i')
        dance:Stop()
    end
end)
