I have installed the points and rewards module v1.60 and had some success. I am now having a problem at checkout. It will not show the points and the discount on the checkout confirm page. It also does not charge the correct amount to paypal. http://www.tennisuniverse.net/store/catalog/ Please feel free to register and try it out. I have not been able to solve this issue. I have tried running through the code, but with little success. Thanks in advance.
