Problems with categories page

[Perlevenn]

I am haveing a problem with my categories page. For some reason, when i push on one of the categories, only a blank page comes up, with this message:

 

1054 - Unknown column 'p.products_id' in 'on clause'

 

select count(p.products_id) as total from products_description pd, products p left join manufacturers m on p.manufacturers_id = m.manufacturers_id, products_to_categories p2c left join specials s on p.products_id = s.products_id where p.products_status = '1' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '1' and p2c.categories_id = '21'

 

[TEP STOP]

 

You can see for yourselves on www.perlevenn.com/catalog. Under "kategorier" in the left coloumb, press on "Ferskvannsperler". This should now show a page of the products i have entered...... However, I only get the error message.

 

What could be wrong? Please help......?
