>How do you plan to store the order field? Is not it already in the table? Why use another field for that?

Considering I haven't been able to look at his entire app, I don't know what "A numeric identifier" does in his table. If it would work here, he can use it, but I'm not sure why he would have asked another question then.

Maybe I'm different, Vlad, but I'd rather address his first general question instead of every aspect of his specific scernario.
