Answer 1

If you haven’t already done so, install Firebug for Firefox, for these reasons:

• it’ll tell you if you have a Javascript error.
• it’ll show you if your Ajax request is being received and its contents.
• you can inspect your page elements such as the cart to see if it’s set to be shown, if the ID is correct, etc. in a much faster way than browsing through the source.
• and more (CSS, etc).

If you can’t figure it out by looking at the Firebug console, and since you’re following a tutorial, why don’t you download the Depot source code and compare it with your own to see what you’re doing wrong.

If you have the book, the complete source is listed at the end of the book. You can also download the source from here.
