I have a site that sells autographs so some product names are the same for example I have 4 Bill Nighy signatures. In a list of Actors the Previous/Next function lists these as 21, 22, 23 and 24 respectively.

BUT in the alphabetical list, clicking on the first Bill Nighy, I would expect Previous/Next to show 21 but it is 23 so consequently when I click next I move to Bill Nighy 24 then another next click gives me the next name in the list - I don't get to see the other 2 Bill Nighy that I know are there because they appear in the alphabetical list.

Something has gone real screwy with the numbering but I can't see what. I've tried altering the Product Info sort order etc but to no avail - the sequencing still sucks.

Any help on this would be greatly appreciated.

The url for the site is:

http://www.movieautographsww.com and the category example is Actors.

Thanks.
