Cgi-Script Adjustment for new server

I have a script that I need working on a new server. It has worked on my previous server. It is a clickable zip code map that shows locations of something within a 100 mile location of where you clicked on the map. The map is working, but am getting errors in the results. It uses a txt format file for the database. I have script and database files. I think it is just a path, permission problem.
