You sure you have jquery 1.3 included in your code? The following works fine (direct copy and paste from your question) for me when I click on any of the LIs:
- |< First Page
- < Prev Page
- 1
- 2
- 3
- Next Page >
- Last Page >|
Are you sure your updateNavigation function is working right? Maybe it's being triggered but something is wrong within it...
