Stocks by attributes

[Arkwright]

What settings do you have on the Admin > Configuration > Stock page?

Can you provide stock values (for product and individual attribute combinations) before and after from a purchase such as you have described?

With regard to Admin>Config>Stock settings, I have them set as below:

Check stock level true
Subtract stock true
Allow Checkout false
Mark product out of stock Out of stock
Stock Re-order level 5
Show available stock level in cart when less than order true
Products status in Catalog when out of stock should be set to 0
Show Sold Out Image in place of Add to Cart 1
Product Quantity Decimals 0
Show Shopping Cart - Delete Checkboxes or Delete Button 3
Show Shopping Cart - Update Cart Button Location 3
Show New Products on empty Shopping Cart Page 1
Show Featured Products on empty Shopping Cart Page 2
Show Special Products on empty Shopping Cart Page 3
Show Upcoming Products on empty Shopping Cart Page 4

Stock levels before purchasing a product:

Total stock 17 items broken down as follows:
Size 8 = 3
Size 10 = 3
Size 12 = 3
Size 14 = 3
size 16 = 2
Size 20 = 3

I have just carried out a test purchase on Size 10 and have ordered 6 of the 3 available.

Toatal stock now reads 11 items, but my stock figures for each attribute haven't changed at all they still read as above.

With regard to my last post, was I correct in the way I was adding a product and adding the stock levels afterwards?

The mystery deepens....
