Issues Tweening FOV

Hey, I’m having issues tweening FOV, for an acceleration script. Basically, whenever the player moves, it increases their walk speed, and tweens their FOV to 120 if they’re moving, otherwise, it gets back the FOV to 70. The issue is the whenever the tween plays, it resets back to the original FOV.

local MaxSpeed = 30
local InitialFOV = 80
local MaxFOV = 120
local FOVTransitionTime = 1

local camera = game.Workspace.CurrentCamera 
local player = game.Players.LocalPlayer
local humanoid = script.Parent.Humanoid

local TweenService = game:GetService("TweenService")

local function setFOV(fov)
	if camera.FieldOfView == fov then
		print("Equal")
		return
	end
	local tweenInfo = TweenInfo.new(FOVTransitionTime, Enum.EasingStyle.Linear)
	local fovTween = TweenService:Create(camera, tweenInfo, { FieldOfView = fov })
	fovTween:Play()
end

local lastMoveDirection = Vector3.new(0, 0, 0)
local isMoving = false

while true do
	wait()

	local moveDirection = humanoid.MoveDirection

	if moveDirection == Vector3.new(0, 0, 0) then
		if isMoving then
			setFOV(InitialFOV)
			isMoving = false
		end
	else
		if not isMoving then
			isMoving = true
			setFOV(MaxFOV)
		end

		humanoid.WalkSpeed = math.min(humanoid.WalkSpeed + 0.8, MaxSpeed)
	end

	if moveDirection ~= lastMoveDirection then
		lastMoveDirection = moveDirection
	end
end

Disregard, seems like the issue was from an outside script.
