Stock variant-how to handle

[chris88]

Hello, i have 2 very important problems that i am trying to solve but i cannot.
I am using joomla 1.5.23 and virtuemart 2.0.12b
1)Even though i have stockable variants in my listed products, the stock number does not update when selecting one. The virtuemart has created children products automatically for these stockable variant products. What can i do about it? I read a lot of things on how to solve it but i cannot figure it out.
2)Also when ordering a product the stock does not update to show the new stock number.
Please help me
Thanks
