Adjustment of Program in Website and make Website run

The website is selling customised suits. Within the website there is an Individualisation Program on which the client can design his garment and which illustrates the design on the website. This function is based on many pictures that are linked to the garment design choices (click one choice i.e. a certain pic is shown). The website exists in german and english. The problem to be sovled: The individualisation tool within the website works perfectly in the english version of the website. After I translated the client choices from english to german (in order to have a german menu) the links for the german website somehow do not work anymore (i.e. there is nomore effects when clicking on the choices, i.e. design garment does not react anymore). - re-link the functions and make the functions work properly for all garments - guidance during testing to solve arising problems Furthermore, a follow-up project linked to this is planned soon - "adjustment of measurement tool" that is on the website. On a later stage i might need a well qualified, responsible and reliable partner to help me maintain the website and solve arising problems.
