465062 need php function adjusted 2

Hi I have swoopo script that has a very common problem according to all the freelancer projects on the freelancer sites. The problem is that when someone hits 'bid' button, the price should increase by the preset increment. However, this does not auto update... the other elements do, but the price does not increase unless the user refreshes their browser. also can you adjust our config file so the people can register. as the emails are not sending out, and we think it is a settings problem. It worked ok on our other server, but this server it is not working. pricewise... keep it real please :)
