 * Hello,
 * I tried to install paypal in welcart. Below is my setting:
    In settlement setting,
   I fill out the API information. In general setting, I select pay with “paypal”
 * I’m able to use Paypal sandbox account to do a test, but when I switch to the
   real account, and click paypal “buy now” button, I got an error message: Your
   order has not been completed
    (error 0)
 * Do you know what’s the problem? Or could you please provide me the procedure 
   of paypal installation?
 * Thanks,
    Min
