The 3 means its the third line I think

Try changing that line to redstone.setOutput("left", true) I would suggest changing the sixth line too as with the above

Also check through and make sure you have spaces in the right places for example on your second to last line between sleep and (1)

Its not very forgiving but is cool when it works!

Hope this helps
