It runs, but twice?

I have made a script for a soda dispenser, but for some strange reason: when the button is clicked, it runs the onCola2 twice!?

Is this because of something in the name, as the other onCola is perfectly fine and does not run more than once when the button is pressed. I copied the onCola2 script from the onCola script, and changed the name, as they are in the same script to avoid spending way too much time making connections between many scripts (dispense boolean). Anyone who can help me?

dispensing = false

cola = script.Parent.b1.Handle
colascript = script.Parent.b1.ApertureColaScript
function makecola()
	dispensing = true
	cola.Transparency = 0
	for i=150,300 do
		cola.CFrame = CFrame.new(6.765, cola.Position.Y + 0.01, 8.622)
		wait()
	end
end

function onCola (player)
	if dispensing == false then
	if not player.Backpack:FindFirstChild("Aperture Cola") then
	makecola ()
	wait(1)
	cola.Transparency = 1
	cola.CFrame = CFrame.new(6.765, 3, 8.622)
	local colanew = cola:Clone()
	local colatool = Instance.new("Tool",player.Backpack)
	local scriptnew = colascript:Clone()
	colatool.Name = "Aperture Cola"
	scriptnew.Parent = colatool
	colanew.Parent = colatool
	colanew.Transparency = 0
	wait(1)
	dispensing = false
	end
	end
end

cola2 = script.Parent.b2.Handle
colascript2 = script.Parent.b2.RepulsionSodaScript
function makecola2()
	dispensing = true
	cola2.Transparency = 0
	for i=150,300 do
		cola2.CFrame = CFrame.new(6.765, cola2.Position.Y + 0.01, 8.622)
		wait()
	end
end

function onCola2 (player)
	if dispensing == false then
	if not player.Backpack:FindFirstChild("Repulsion Soda") then
	makecola2 ()
	wait(1)
	cola2.Transparency = 1
	cola2.CFrame = CFrame.new(6.765, 3, 8.622)
	local colanew = cola2:Clone()
	local colatool = Instance.new("Tool",player.Backpack)
	local scriptnew = colascript2:Clone()
	colatool.Name = "Repulsion Soda"
	scriptnew.Parent = colatool
	colanew.Parent = colatool
	colanew.Transparency = 0
	wait(1)
	dispensing = false
	end
	end
end

script.Parent.b2.b2.ClickDetector.MouseClick:connect(onCola2)
script.Parent.b1.b1.ClickDetector.MouseClick:connect(onCola)

NVM I fixed it. Remember me saying: I put it all in one script to avoid making connections between scripts? Well, I had forgotten to take away the earlier script. But I guess this answered the question anyways.
