Pesky - With Recently Viewed Items

The URL is [url]

Two problems with a recently viewed items script. One is an undefined that's getting written with each iteration. How do I get rid of the string of 'undefined'?

The other is that the items write out in the reverse of the order I want them in. I suppose I could just make the containing <div> tags float: right; instead of float: left; and fix this, but it would look odd when only 1 or 2 items have been viewed. I'd like item 1 to display to the far left, then shift to the right as additional items are viewed. Recently viewed items show horizontally at the bottom of the page content, above the footer.

The JS for the recent items is:

The script embeded in each page to pass values to the above looks like:
