[jQuery] Opera Issues

Hi,
I'm working on the below site:
http://www.toomanydesigns.com/test/TMD/
I just tested it in the main browsers and it works fine apart from
Opera.
I understand the text positioning because Opera doesn't support this
but does anyone know why the barcode slider isn't working correctly?
I'm new to jQuery so it'sprobably somthing stupid on my part.
Thanks
