Can someone look over this database as I'm not sure it's right. A friend gave me the database saying it should work but I cant get query results from it.

I think there maybe problems with the relationships or something.

The database is for pruducts that need to be pulled into a website, I'm using dreamweaver MX to do this.

The database is for a online shops products, Product Name, Description... etc. Some products have a size and some have colours some have both size and colour, also some of these are without size and colour atributes.

I feel somewhat out of depth on this one... HELP!
