My UIS Input Began event isn't working? [SOLVED]

Okay, so I made this cool script, it puts air particles around the user's body and buffs their stats. The script was a Local Script, and when I was testing with some other people, they couldn't see it when I activated it. I figured that FE was to blame, since it was a local script, so I tried making it a normal script, and now the UIS Input Began event doesn't do anything. Can UIS only be used in a local script? If so, what else can I use to substitute it?

Script:

local player = game.Players:WaitForChild(script.Parent.Parent.Name)
local char = player.Character
local humanoid = char:WaitForChild("Humanoid")
local UIS = game:GetService("UserInputService")
local enabled = script:WaitForChild("LimitBreaker")
enabled.Value = false
local enableKey = Enum.KeyCode.Q

local stats = player:WaitForChild("leaderstats")
local level = stats:WaitForChild("Level")

local staminaStuff = player:WaitForChild("StaminaStuff")
local stamina = staminaStuff:WaitForChild("Stamina")
local drain = 2

local otherStats = player:WaitForChild("Stats")

local strengthF = otherStats:WaitForChild("Strength")
local strength = strengthF:WaitForChild("StrengthLevel")

local speedF = otherStats:WaitForChild("Agility")
local speed = speedF:WaitForChild("AgilityLevel")

local jumpF = otherStats:WaitForChild("Jump")
local jump = jumpF:WaitForChild("JumpLevel")

local multiplier = 2

	UIS.InputBegan:connect(function(key)
		if key.KeyCode == enableKey then
			if level.Value >= 200 and stamina.Value>= 0 then
				if enabled.Value == false then
					enabled.Value = true
