Trying to make spells work and visible to everyone. How do I fix my code?

So I have two scripts. One is local script in StarterGui and another one is in Workspace. the script in Workspace is a normal script. I was wondering if someone can point out what I am doing wrong and correct me. Im fairly new at remote events.

Code in workspace: local ReplicatedStorage = game:GetService("ReplicatedStorage")

local createPartEvent = ReplicatedStorage:FindFirstChild("Spells")

local cooldown = "on"

local function Recieved(Players)

if cooldown ~= "off" then

local torso = Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart")

local Part = Instance.new("Part")

Part.Parent = torso

Part.CFrame = torso.CFrame + torso.CFrame.LookVector * 10

cooldown = "off"

wait(10)

cooldown = "on"

wait(10)

Part:Destroy()

end

end

createPartEvent.OnServerEvent:Connect(Recieved)

------------------------Local script:

local Players = game:GetService("Players")

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Spells = ReplicatedStorage:WaitForChild("Spells")

local UIS = game:GetService("UserInputService")

local cooldown = "on"

UIS.InputBegan:Connect(function(input)

if input.UserInputType == Enum.UserInputType.Keyboard then -- Checks if the input was related to a keyboard

if input.KeyCode == Enum.KeyCode.Q then

if Players.LocalPlayer.Character then

Spells:FireServer()

end

end

end

end)
