Rich, You're certainly right. However I've actually simplified the table structure here in order to not over-complicate matters. I'm pretty certain the schema is good, but if you have the time/willingness to work through the whole thing with me, my AIM is NeonNinjaSan or ICQ 51549640 - I don't want to waste your time if you don't have it though. Cheers.
Also, to answer your question, yes an object with the property "green" might also have the property "yellow" with a different score. Rich Shepard wrote: > > Why have the ID columns?
