I'm trying to implement qty by attribute for my 1.3.7 site so I can sell shirts in the holiday season.

So far, I'm not having luck. I suspect it's due to the module needing 1.3.8, can someone confirm this?

Can someone point me to something that WILL work for my 1.3.7 cart?

When I did install this, I was able to see the back end and it appeared to work. I.e. I could put in 3 small shirts and 4 mediums and then hit the update link and the main product showed qty of 7 with the appropriate sub-qty. But then, when I went on the front end and purchased 1 small shirt, I would see the main qty go to 6 on the admin view but the sub-qty for small would STAY at 3. The behavior I expected to see was that both the main qty AND the sub-qty would go down.

If I went to the front end and tried to order 4 small shirts, it would tell me there were not 4 available, which is correct. But then I could still order 3 since the sub-qty remained at 3, but in reality I would only have 2 available at this point.

So I'm thinking that either my cart version is not compatible with this and I hope someone can point me to something that works (doesn't need to be fancy). Or, I have misunderstood the purpose of this mod and someone can point me to something more appropriate for my needs. Or .... something else :)

Any help or direction is appreciated.
