[login to view URL] [login to view URL] Hi I need some one's help to install above two contributions. It should be worked on oscommerce-2.2rc2a and all errors should be fixed. I will install a clean oscommerce on my server, no files has been modified, so it will be easy for a REAL programmer. This is my second time to ask somebody to install the coupon module, my first project was given to expertMan and he has cheated my money by giving me unworking files. I have learned from this lesson. In order to avoid lame bidder, 150++ positive review is a must.
