Is this possible?

Hi! I have this tricky case, at lest for me : ) I'm trying to get some data out of two tables and listing the data in a product/price site. But..... : I have one table with productinfo and one with prices. And it is several columns with the same id in the pricetable, because every product have several sizes. So... how do I get only one row from the "product table" and two rows from the "price table" in one line in a page? Is it possible? Best regards Raymond
