Ordered and sold- double store for attributes...

HEllo the one seems a serious trouble,or a a bad way to work,listen

I 'm doing a work with zen,
My boss asked me to know how many shirt he sell at the end of month to
re order it.
i have several hundred of models of this shirts.....

I have 100 shirts stocks,
the user have to choose between 2 colors....

How many red color shirts i sold, instead of black shirts ????

The number of shirts i have in stock become unuseful,maybe???
There's something i lost?...

Please telll me...

Thanks

Ps. the solution becomes to double the full database to add a color option and be sure of the numbers..... isn't possible, i missed something...

Zen Cart does not have inventory by attributes at this moment. It is coming a in a future release.

...ok...

.... just waiting for next release... :)
Thanks.
