Tiled Background?

I am following the tutorial here: http://www.kirupa.com/developer/mx2004/duplicatebackground.htm

And all that happens is I get one copy of my image in the bottom right corner, not tiled. I have copied the code exactly. Is there a problem with the code?

Can someone show me how to create a tiled background image? Thanks.
