[login to view URL] the coder job is to check and repair every link , broke link or broke text that depends on the script. [login to view URL] the programmer in case there are some pages with the headers of the design not implemented, the programer must implement it on those pages , the design is already done but some pages do not have the header pointed to the right footer or header location. 4. the programmer must install the R3N3 payment gateway as well , we have the script bought from [login to view URL] So the whole job is to test, retest, repair, imlement payment and design headers for script so that everyting should be ready for lounch.
