What is wrong with this script?

I want it so my door SLIDES to the right (when you are facing the door) and when you click it again, it slides back, click it again slides to the right and so on. However, my script makes my door rotate 90 degrees then breaks. It does not rotate back when you click it again. Here is my script

local brick = script.Parent.brick
local c = true

function OnC()
	if c == true then
		c = false
		brick.CFrame = CFrame.new(-39.2, 4.69, -53.3)
		
	end
	if c == false then
		c = true
		brick.CFrame = CFrame.new(-39.2, 4.69, -46.8)
	end
end

brick.ClickDetector.MouseClick:connect(OnC)

What is wrong with it?

local brick = script.Parent.brick
local c = true

function OnC()
    if c == true then
        c = false
        brick.CFrame = CFrame.new(-39.2, 4.69, -53.3)
-- the end was here, it shouldn't have been.		


    elseif c == false then -- changed this to elseif
        c = true
        brick.CFrame = CFrame.new(-39.2, 4.69, -46.8)
    end
end

brick.ClickDetector.MouseClick:connect(OnC)

What was wrong is that you had an end.. and you didn't do an elseif.. So it only processed the first part.
