How to make a script for keybind crouch animation?

I have my crouch Animation ready, But I don't know how to prepare a script for making it keybind. I I want it such that when I press 'c', I can crouch and when I press 'c' again, I can revert back to normal position. Can you please help me for giving me the script for that?

local player = game.Players.LocalPlayer
02	local mouse = player:GetMouse()
03	local Character = player.Character or player.CharacterAdded:Wait()
04	local Humanoid = Character:WaitForChild("Humanoid")
05	local UIS = game:GetService("UserInputService")
06	 
07	local debounce = false
08	UIS.InputBegan:Connect(function(Input)
09	    if Input.KeyCode == Enum.KeyCode.C then
10	        if not debounce then
11	            debounce = true
12	            local Animation = Instance.new("Animation")
13	            Animation.AnimationId = "rbxassetid://4851457147"
14	            Animation.Parent = player.Character
15	            Animate = Humanoid:LoadAnimation(Animation)
16	            Animate:Play()
17	        else
18	            Animate:Stop()
19	 
20	            debounce = false
21	        end
22	    end 
23	end)

``

this is my current script and is not working.
