How to change the distance the doors move apart?

Got this script from a sliding door I found, but being me I don't know most of what is going on in the script. I just need to know how and where to change the distance the doors move apart in the script.

door = script.Parent
door1 = door.Door1
door2 = door.Door2
button = door.Button
isopen = door.IsOpen
debounce = door.Debounce

button.ClickDetector.MouseClick:connect(function()
	if (debounce.Value == false) then
		if (isopen.Value == true) then
			isopen.Value = false
		elseif (isopen.Value == false) then
			isopen.Value = true
		end
		button.BrickColor = BrickColor.new("Black")
	end
end)

isopen.Changed:connect(function()
	if (debounce.Value == false) then
		debounce.Value = true
		if (isopen.Value == true) then
			for i=1, 190 do
				door1.CFrame = door1.CFrame * CFrame.new(-0.1,0,0)
				door2.CFrame = door2.CFrame * CFrame.new(0.1,0,0)
				wait()
			end
			debounce.Value = false
			button.BrickColor = BrickColor.new("Bright red")
			return
		end
		if (isopen.Value == false) then
			for i=1, 190 do
				door1.CFrame = door1.CFrame * CFrame.new(0.1,0,0)
				door2.CFrame = door2.CFrame * CFrame.new(-0.1,0,0)
				wait()
			end
			debounce.Value = false
			button.BrickColor = BrickColor.new("Bright green")
			return
		end
	end
end)
