We're running on an heavy modified verison of OsCommerce, and now we need to start with a little check on the quantity behaviour.
We have one warehouse and one shop, and both have different quantity management. We've implemented funtion to merge and split order, to delete multiple ones and so on. Somehow sometimes (often to say the truth) we find wrong quantities in the warehouse or in the shop, and this is irritating.
We need someone to check were the error is, and fix it.
