Trouble with Kirupa's RPG tutorial

I was cruising through the tutorial, but when I get to this:

Specifically, the item generation. It just doesn’t work.

I have changed the instance names to the correct things, but my hero still doesn’t appear.

I suspect it may have to do with the “items” object that comes up.

_root.attachMovie(“blank”, “items”, this.getNextHighestDepth());

_root.items.attachMovie(“Hero”, “heroguy”, d++);
_root.items.heroguy._x = (_root.tileWdthj);
_root.items.heroguy._y = (_root.tileHght

Never in the tutorial did it say to create an “item” object.
