I want users can offer a reward (Userpoints)for their question.Once user create a question and set up a reward amount,system will deduct userpoints that they set from their total userpoints.If user confirm the question is solved by someone's answer,then the reward will transfer to the user who answer the question.I have installed Userpoints and Answer.But I down know how to realize above mention fuction.it there any module can do that?
