when i equip the tool and press Q nothing happens, what should I do?

--Varables
local Form1 = script:WaitForChild("FirstForm")
local equipped = false
local UIS = game:GetService("UserInputService")
local tool = game.StarterPack.Sword


--Animate
tool.Equipped:Connect(function()
    equipped = true
end)

tool.Unequipped:Connect(function()
    equipped = false
end)

UIS.InputBegan:Connect(function(Input, isChatting)
    if isChatting then return end
    if Input.KeyCode == Enum.KeyCode.Q and equipped == true then

        local Humanoid = tool.Parent:WaitForChild("Humanoid")
        local AnimTrack = Humanoid:LoadAnimation(Form1)

        AnimTrack:Play()
    end
end)
