I need help with animations

Help and Feedback Scripting Support
1

Sorry for my bad grammar, English is not my first language

  1. What do you want to achieve?
    When I hold shift or C the animation will play

  2. What is the issue?
    The animation plays before I wanted it to

  3. What solutions have you tried so far?
    I have tried to look up on API Reference on roblox

The code(Local script):

local Character = workspace:WaitForChild(Player.Name)
local Humanoid = Character:WaitForChild('Humanoid')

local RunAnimation = Instance.new('Animation')
RunAnimation.AnimationId = ""
local RAnimation = Humanoid:LoadAnimation(RunAnimation)

local CrouchAnimation = Instance.new('Animation')
CrouchAnimation.AnimationId = ""
local CAnimation = Humanoid:LoadAnimation(RunAnimation)

local CrouchIdleAnimation = Instance.new('Animation')
CrouchIdleAnimation.AnimationId = ""
local CIAnimation = Humanoid:LoadAnimation(RunAnimation)

local ContextActionService = game:GetService("ContextActionService")

local CrouchingSpeed = 5
local RunSpeed = 20 
local DefultSpeed = 10 

local Holding = false
local Running = false
local Crouching = false

local function Run()
	if Player:FindFirstChild("Crouching") ~= nil and Crouching == false then
		if Holding == false then
			Holding = true
			RAnimation:Play()
			print("Running")
			Humanoid.WalkSpeed = RunSpeed
			Running = true
		else
			print("Stopped running")
			Running = false
			Holding = false
			RAnimation:Stop()
			Humanoid.WalkSpeed = DefultSpeed
		end
	end
end

local function Crouch()
	if Player:FindFirstChild("Crouching") ~= nil and Running == false then
		if Holding == false then
			Crouching = true
			Holding = true
			print("crouching")
			Player.Crouching.Value = true
			CAnimation:Play()
			Humanoid.WalkSpeed = CrouchingSpeed
		else
			Crouching = false
			Holding = false
			print("stoppped crouch")
			Player.Crouching.Value = false
			CAnimation:Stop()
			Humanoid.WalkSpeed = DefultSpeed
		end
	end
end

ContextActionService:BindAction("Run", Run, true, Enum.KeyCode.LeftShift)
ContextActionService:SetTitle("Run", "Run")
ContextActionService:SetPosition("Run",UDim2.new())

ContextActionService:BindAction("Crouch", Crouch, true, Enum.KeyCode.C)
ContextActionService:SetTitle("Crouch", "Crouch")
ContextActionService:SetPosition("Crouch",UDim2.new())


Humanoid.StateChanged:Connect(function(OldState, NewState)
	if NewState == Enum.HumanoidStateType.RunningNoPhysics then
		CIAnimation:Play()
		print("idle")
	else
		print("not idle")
		CIAnimation:Stop()
	end
end)

I know local script is a bad idea for this but my game won’t be popular so I don’t really care
