Attempt to index upvalue 'UsingMove' (a boolean value) and Debounce issue [?]

#Goal:# My goal is to create a debounced move, this seems extremely simple but for some reason, it's not working. Currently, it works the first time I join but doesn't work anymore. It does give me an error though

#Script:# Module (ReplicatedStorage):

local MovesInfo = {
	Fireball = {
		Damage = 4;
		Cooldown = 5;
	};
};
return MovesInfo

LocalScript (StarterCharacterScripts):

local QDebounce = true

local Animations = {
	GreatFireBall = ReplicatedStorage.Animations['Great Fire Ball Animation [0.7]'];
}

local RE = {
	GreatFireBall = ReplicatedStorage.RemoteEvents.Moves['Great Fireball'];
}

local function FunctionLoadAndPlay(Humanoid, Move)
	if Move == 'Fireball' then
		local Animation = Humanoid:LoadAnimation(Animations.GreatFireBall)
		Animation:Play()
	end
end

UIS.InputBegan:Connect(function(Input, IsTyping)
	if IsTyping then return end
	local KeyCode = Input.KeyCode
	print(QDebounce)
	if QDebounce and KeyCode == Enum.KeyCode.Q and Char and UsingMove then
		local Move = Q.Value
		QDebounce = false
		print(QDebounce)
		UsingMove.Value = true
		RE.GreatFireBall:FireServer(Mouse.Hit, Move)
		FunctionLoadAndPlay(Humanoid, Move)
		wait(0.7)
		print(QDebounce)
		UsingMove = false
		wait(Moves.Fireball.Cooldown)
		QDebounce = true
		print(QDebounce)
	end
end)

Note that QDebounce is local QDebounce = true as a variable

#Prints:# true (x17) false false true true (x50)

Error: 17:00:45.501 - Workspace.BlackOrange3343_YT.Moves:48: attempt to index upvalue 'UsingMove' (a boolean value) 17:00:45.504 - Stack Begin 17:00:45.506 - Script 'Workspace.BlackOrange3343_YT.Moves', Line 48 17:00:45.508 - Stack End

which is if QDebounce and KeyCode == Enum.KeyCode.Q and Char and UsingMove then

I don't see why it works once but doesn't a second time.

How can I fix this? I Appreciate any helpful feedback thank you for reading.
