custom field and stock control

[meet_rayhan]

Hi,

If I add a custom field like "Color" and/or "Size" and I have different product stocks for different type of colors/sizes, how can I control stock value according to sale of product? If I put combined total, there's no way to control as certain color may be out of stock but according to combined total, it is still available and customer will proceed to place an order and checkout.

Can anyone shed lights on this issue to control inventory stock according to custom field?

Thanks,
Rayhan

I found this URL but it has not finished. I followed instructions but I can not see child products on my front end?  The only difference I have noticed on parent product that description contains "Color Stock-Red" (i.e.%CUSTOM_FIELD_NAME%)

Any one guide me on this one?
