Simple Mining Turtle /Need help/

Hello everybody

I'm pretty new in the ComputerCraft mod and jsut getting started. I watched some videos and guides before i started to write my first programm which shall simple stripmine for me. I dont realy know anyhow about how to fix the error, for me, the program seems fine. I would be pleasured if you could help my out!

Here the pastebin link for my program: http://pastebin.com/xHgkj1Ez

Please post the error, as it includes valuable information such as the line number. I looked over you code quickly, nothing stood out as being blatantly wrong.

Line 29 missing parentheses.
Line 32 missing "do".

Moved to Ask a Pro.

I have fixed 2 errors and change while to if just to make more compact

function mine()
    turtle.dig()
    os.sleep(0.5)
    if turtle.detect() then
	    turtle.dig()
	    os.sleep(0.5)
    end
    turtle.forward()
    turtle.digDown()
    turtle.digUp()
    os.sleep(0.5)
    if turtle.detectUp() then
	    turtle.digUp()
	    os.sleep(0.5)
    end
end
