How to stop OnClientEvent(?) from firing multiple times?

[DUYRN115 (Shell)]

I have a function that detects M1 inputs from the client, then it fires a remote event “m1In” to the server to create stats for a hitbox, then it fires another remote event “m1Out” back to the client. The issue here is when i tested the OnClientEvent of m1Out, the first left click seems to just give out 1 output like it should be; however on the second click, it gives the output twice, and on the third click it gives the output three times and so on. My question is how can I fix this issue cause im not sure if it’s about the inputbegan or its about the onclientevent.

Here’s my function:

local connection
function M1Detect()
	if connection == nil then
		connection = UIS.InputBegan:Connect(function(inp, gp)
			if gp then return end

			if inp.UserInputType == Enum.UserInputType.MouseButton1 then
				checkEndLag = plr:WaitForChild("PlayerStates"):WaitForChild("EndLag").Value
				if checkEndLag or m1AnimDebounce then return end

				local animID = returnM1Count(m1count, 6)
				local anim = script.M1
				anim.AnimationId = animID
				local animPlay = plr.Humanoid:LoadAnimation(anim)

				m1count += 1
				m1AnimDebounce = true
				if m1count > 5 then m1count = 1 comboEnder = true end

				M1In:FireServer(comboEnder)
				local timeTaken
				M1Out.OnClientEvent:Connect(function(size, key, offset, dur, ogTime)

					timeTaken = os.clock() - ogTime

					local box = Instance.new("Part")
					box.Parent = workspace
					box.Anchored = true
					box.CanCollide = false
					box.Size = size
					box.Transparency = 0.9
					box.Color = Color3.new(1, 0, 0)
					box.CFrame = plr.HumanoidRootPart.CFrame * CFrame.new(offset.X, offset.Y, offset.Z)

					game.Debris:AddItem(box, dur)			
				end)
				task.wait(timeTaken)
				animPlay:Play()
				animPlay.Stopped:Wait()
				if comboEnder then comboEnder = false end
				m1AnimDebounce = false
			end
		end)
	end
end```

M1Out.OnClientEvent:Connect

You need to disconnect the connection

i tried adding a disconnect for connection at the end but it just ended up disabling the function forever, like it only detects my click once and stops

Okay, but i’m talking about the OnClientEvent connection, if you do not ever disconnect it then every time you’ll be receiving multiple executions, cause on every click you’re connecting a new connection, so move this outside the InputBegan connection or disconnect It after it has executed.
