I can't get my dart script to create a mesh. How would I do this?

Hi everyone. I am trying to script a dart gun for a game I'm working on. The gun uses some simple remote events to communicate client to server.

The local script tests to see if the tool is equipped and is supposed to fire server. The server reads this and creates the dart projectile and mesh.

Then the local script sends another signal when the tool is clicked to clone the mesh.

Local script below: IGNORE VARIABLES

--Constraints
local IgnoreList = {rocket = 0, handle = 1, effect = 1, water = 1} -- Rocket will fly through things named these
--NOTE: Keys must be lowercase, values must evaluate to true
--Variables
local tool = script.Parent

local player = game.GetService("Players").LocalPlayer

local mouse = player:GetMouse()
-----InTool
local configs = game.ReplicatedStorage.MaverickConfigurations
local gungui = tool:WaitForChild("GunGUI" )
local firesound = tool.WaitForChild("FireSound")
local reloadsound = tool.WaitForChild("ReloadSound")
local primesound = tool.WaitForChild("PrimeSound")
local reloading = false --reloading check

local priming = false -- priming check

local capacity = configs.Capacity.Value

local gravityacceleration = 196.2

local dartmeshid = 'rbxassetid://2906043627'

local meshscale = Vector3.new(0.17,0.17,.25)

local dartpartscale = Vector3.new(1, 1, 1)

local dartcolor = BrickColor.new(33, 60, 122)

local spawnPosition = tool.Model.Muzzle.CFrame()

--local contextActionService = game:GetService("ContextActionService") 
--caters to mobile gamers (A Later Update)

local bodytype = nil

local difference = 0 -- dif between head and mouse

local replicatedstorage = game:GetService("ReplicatedStorage")

local gungui = tool:WaitForChild("GunGUI")

--remote events
local equipAnimation = replicatedstorage:WaitForChild("EquipAnimation")

local unequipanimation = replicatedstorage:WaitForChild("UnequipAnimation")

local primeAnimation = replicatedstorage:WaitForChild("PrimeAnimation")

local shootevent = replicatedstorage:WaitForChild("ShootEvent")

local prime = replicatedstorage:WaitForChild("Prime")

local reload = replicatedstorage:WaitForChild("Reload")

local equip = replicatedstorage:WaitForChild("Equip")

local headshot = replicatedstorage:WaitForChild("Headshot")
--remote functions
local checkBodyType = replicatedstorage:WaitForChild("CheckBodyType")

local fetchRemainingAmmo = replicatedstorage:WaitForChild("FetchRemainingAmmo")


--When tool is equipped this script will run
tool.Equipped:Connect(function(mouse)
	replicatedstorage.equip:FireServer(mouse)
	gungui:Clone().Parent = player.PlayerGui -- cloning gui into player on equip
	equipAnimation:FireServer(tool.shoot) -- calling remote event to add to server equip animation
	mouse.Icon = "rbxassetid://3862353028"
	
	end)

local function OnActivated() --shoot!
	if reloading == true or priming == true 
	then
		--
	else
		replicatedstorage.ShootEvent:FireServer(spawnPosition,tool)
		
		end
	
	end

Server Script:

local player = game.Players.LocalPlayer
local replicated = game:GetService("ReplicatedStorage")
local configs = replicated:WaitForChild("MaverickConfigurations")
local coolDown = configs.AttackCooldown.Value
local Gravity = 196.2
local reloadtime = configs.ReloadTime.Value -- Seconds until tool can be used again
local dartspeed = configs.DartSpeed.Value -- Speed of the projectile
local dartmesh = 'http://www.roblox.com/asset/?id=2251534'
local meshscale = Vector3.new(0.35, 0.35, 0.25)
local dartsize = Vector3.new(1.2, 1.2, 3.27)



game.ReplicatedStorage.MaverickConfigurations.Equip.OnServerEvent:Connect(function(player, mouse)
--NOTE: We create the dart once and then clone it when the player fires
local Dart = Instance.new('Part') do
	-- Set up the dart part
	Dart.Name = 'Dart'
	Dart.FormFactor = Enum.FormFactor.Custom --NOTE: This must be done before changing Size
	Dart.Size = dartsize
	Dart.CanCollide = false

	-- Add the mesh
	local mesh = Instance.new('SpecialMesh', Dart)
	mesh.MeshId = dartmesh
	mesh.Scale = meshscale

	-- Add a force to counteract gravity
	local bodyForce = Instance.new('BodyForce', Dart)
	bodyForce.Name = 'Antigravity'
	bodyForce.force = Vector3.new(0, Dart:GetMass() * Gravity, 0)

	-- Finally, clone the dart script and enable it
--	local dartScriptClone = DartScript:Clone()
--	dartScriptClone.Parent = Dart
--	dartScriptClone.Disabled = false
end

	
game.ReplicatedStorage.MaverickConfigurations.ShootEvent.OnServerEvent:Connect(function(player,spawnPosition,tool)
		-- Create a clone of dart and set its color
		local dartClone = Dart:Clone()
		--game.Debris:AddItem(dartClone, 30)
		dartClone.BrickColor = BrickColor.new(33, 60, 122)
		-- Position the dart clone and launch!
		dartClone.CFrame = CFrame.new(spawnPosition, target) --NOTE: This must be done before assigning Parent
		dartClone.Velocity = dartClone.CFrame.lookVector * dart_SPEED --NOTE: This should be done before assigning Parent
		dartClone.Parent = game.Workspace		
		
		delay(coolDown, function()
		
		end)
	
		spawn(function()
			wait(30)
			if dartClone then dartClone:Destroy()

Thanks for your help everyone!
