How do I properly add to an intvalue?

Okay. So I made a part that when someone touches it, the intvalue goes up by 1 and when someone clicks on a button that value goes down by 1. The problem is that after someone clicked that button, the value goes down by 1, but after when someone touched the part to add to the value, it adds up 2 instead of 1. Here is the script in the part:

script.Parent.Touched:Connect(function(hit)
	if script.Parent.Reload.Value == false then
		if hit.Parent:FindFirstChild("Humanoid") ~= nil then
			if script.Parent.Players.Value < 5 then
				script.Parent.Reload.Value = true
				script.Parent.Players.Value = script.Parent.Players.Value +1
`the "Players" is the name of the value`
				hit.Parent.HumanoidRootPart.CFrame = CFrame.new(game.Workspace.BallonPart.Position)
				local gui = game.ReplicatedStorage.ScreenGui:Clone()
				gui.Parent = game.Players:WaitForChild(hit.Parent.Name).PlayerGui
			end
		end
	end
	wait(2)
	script.Parent.Reload.Value = false
end)

and here's the script in the button:

script.Parent.MouseButton1Click:Connect(function()
	game.Players.LocalPlayer.Character.HumanoidRootPart.CFrame = CFrame.new(game.Workspace.SpawnLocation.Position)
	game.Workspace.Part.Players.Value = game.Workspace.Part.Players.Value -1
	script.Parent.Parent.Parent:Destroy()
end)

I think that the 1st script is ignoring the changes made from the 2nd script, so it just keeps adding, but idk how to fix it. Altough the 2nd script isn't ignoring, because it is renewed every time (cloned and destroyed) so it forgets the value of the intvalue.

I'm sure that there is an way out of that and help will be appreciated!
