Moving Brick Button [Help Needed]?

Basically I just need help on the part of the code where the block will return I have it set to wait 2 seconds then it will move back by it's self, but I want it to move back once I click the button again. Could I get some help please? Thanks!

d = false
function onClicked()
    if d == false then
        d = true

        print("Moving Brick To Right")
        script.Parent.Parent.DoorButton.BrickColor = BrickColor.new("Really red")
        for i = 1,49 do
        script.Parent.Parent.Door.CFrame = script.Parent.Parent.Door.CFrame * CFrame.new(0, 0, 0.244) * CFrame.fromEulerAnglesXYZ(0,0,0)
        wait()
        end

        -- I need this section to move after I click the brick once again but I can't figure it out
        wait(2)
        script.Parent.Parent.DoorButton.BrickColor = BrickColor.new("Lime green")
        print("Moving Brick To Left")
        for i = 1,49 do
        script.Parent.Parent.Door.CFrame = script.Parent.Parent.Door.CFrame * CFrame.new(0, 0, -0.244) * CFrame.fromEulerAnglesXYZ(0,0,0)
        wait()
        end
        d = false
        end
    end
script.Parent.ClickDetector.MouseClick:connect(onClicked)
