PS_OS_ERROR Stock return

[mufo]

Hello,

 

My payment module automatic use those status:

 

PS_OS_PREPARATION -> PS_OS_PREPARATION when the payment is approved and its ok..

but when the payment failed because cart credit dont have money the status is:

 

PS_OS_PREPARATION -> PS_OS_ERROR

 

My problem is: the stock dont back.

Example: i have 1 ipod to sell.. the paymment is declined by PS_OS_ERROR and now i have 0 IPOD in my stock.

 

Its possible to make PS_OS_ERROR turn back my stock?

Or set only to stock remove when status is PS_PAYMENT for example?

 

thank you, sorry for my bad english
