Combination Product problem

[colorlife]

Hello i use 1.6.1.4 and i have some problem with product grouped. I hope anyone can help me.

 

For example i have a product:

 

- Product A: quantity 1000 piece

- Product B: quantity 1500 piece

 

For each product i setting the quantity manually and i sync with external warehouse.

 

I create a grouped product with Product A + Product B and setting, for quantity:

"I want to use the advanced stock management system for this product." (same each product single) and "The available quantities for the current product and its combinations are based on the stock in your warehouse (using the advanced stock management system)." and "Decrement both."

The problem is that i can't see the quantity. I see the quantity like 0 and not 1000 (the maximun quantity of one product).

How can i set correctly?

Thanks
