How do I make it so that the moving-while-crouching-animation plays only if you move?

Basically, I've made it so that if you hold LCtrl (using UIS) it lets you crouch, but the problem is, the moving-while-crouching-animation plays even when you're not moving. I've made use of GetState() but it doesn't seem to work. Here's the block of code.

-------------------------
----VARIABLES----
-------------------------
local UIS = game:GetService("UserInputService")
local player = game.Player.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")
crouched = false
moving = false

--------------------------
----ANIMATIONS----
--------------------------
local crouchedanim = Instance.new("Animation")
crouchedanim.Parent = character
crouchedanim.Name = "CrouchedAnim"
crouchedanim.AnimationId = "rbxassetid://556017"

local crouchedtrack = humanoid:LoadAnimation(crouchedanim)

local crouchmoving = Instance.new("Animation")
crouchmoving.Parent = character
crouchmoving.Name = "MovingCrouchAnim"
crouchmoving.AnimationId = "rbxassetid://551730"

local crouchmovetrack = humanoid:LoadAnimation(crouchedanim)

UIS.InputBegan:Connect(function(key)
if key.KeyCode == Enum.KeyCode.LeftControl then
crouched = true
if not moving then
crouchedtrack:Play()
humanoid.WalkSpeed = 5
elseif moving then
crouchmovetrack:Play()

UIS.InputEnded:Connect(function(key)
if key.KeyCode == Enum.KeyCode.LeftControl then
crouched = false
crouchedtrack:Stop()
crouchmovetrack:Stop()
humanoid.WalkSpeed = 16




humanoid.StateChanged:Connect(function(oldState, newState)
if newState == Enum.HumanoidStateType.Running then
moving = true
else
moving = false

ignore the fact that there are no ends or spacing, i just typed it up here cause i have no time to open roblox studio (and i am 100% sure that that's the exact code)

Basically, the problem here is that the moving-while-crouched animation still plays even when the player is not running. How do I fix this, how do I make it work?

theres an event called humanoid.Running which runs when the player is running, you can use the first parameter which is speed, if the speed is 0, that means player is standing still, so try replacing the stateChanged event with running event

humanoid.Running:Connect(function(speed)
	if speed > 0 then
		-- Running
		moving = true
	else
		-- Stopped
		moving = false
	end
end)

you are also missing a lot of ends

Edit:

you didn't stop the other anim

UIS.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.LeftControl then
		crouched = true
		if moving then
			crouchedtrack:Stop()
			crouchmoving:Play()
		else
			crouchedtrack:Play()
			crouchmoving:Stop()	
		end
	end
end
