Product listing: check two category fields

Hi,

I do have a listing of musical works. On a one page layout, it selects works from different categories ID and put them under subtitles.

For now this is my code (which is working) but I need it to check "categorie2" field each time as well because some works appear in 2 different categories (I made two categories fields in my "works" table).

Thanks for your help

Jeremy
