How do I make more than 1 gate open from one trigger?

Okay, so far I have this script. The model link is: http://www.roblox.com/First-GUI-Controlled-gate-item?id=153689396

--Made by iEternalFire. (Creator of the first GUI gate)
local trigger = script.Parent
local gate = game.Workspace.Gate

moving = false
open = false

function onClick()

    if open == false and moving == false then

        moving = true
        script.Parent.Text = "Open Gate"
        for i = 1, (gate.Size.Y * 10 + 1) do
            wait()
            gate.CFrame = gate.CFrame*CFrame.new(0, -0.1, 0)
        end

        moving = false
        open = true

    elseif open == true and moving == false then

        moving = true
        script.Parent.Text = "Close Gate"
        for i = 1, (gate.Size.Y * 10 + 1) do
            wait()
            gate.CFrame = gate.CFrame*CFrame.new(0, 0.1, 0)
        end

        moving = false
        open = false

    end

end

script.Parent.MouseButton1Down:connect(onClick)
