Attribute = new item

[TaNo]

Hello all,
i'm facing a problem with my catalog.
first of all, I apologize for my english.
I'll try to explain my problem:
I'm into the jewellery business, so suppose u have a necklace that is 18 inches long, i add it into my catalog, but i also have the same necklace in 20 inches, 22 inches and over. Now, my problem is, eventhough the size is different, for me it is a different article(item).
If i add attriubtes for the lenght, it will change my price if i want to, but it will consider it the same article.
I know there is a contribution that will allow me to keep a stock level for attributes...but it is not exactely what i was looking for, since i give to my online products a code (95959595) related to my intranet database, and i need each item to keep its unique code.
I don't know how clear i've been, please let me know if my post is understandable otherwise i'll try to explain better.
thanks a lot,
TaNo

Use this "model" number/code to corispond with your OFFLINE intranet database.

Did you find all the code it said to look for - or was it modified?
