160794 Troubleshoot Real Estate Scrip

I have a real estate database driven website which does not appear to be working properly. The script imports .ZIP files from a flat text database daily on a Cron, then these files are ported to a SQL database which then displays the data within my real estate website. All the code is written and appears to be working except that some of the listings are not showing up, while others are. You should have a complete understanding of server scripting in perl and PHP as well as an understanding of cron, wget and other basic unix commands. You should have a complete understanding of mysql and PHP. Your job is to examine the processes and identify the errors which are causing the problems and then carefully write a report explaining what is wrong, and how to fix it. You are not required to fix the scripts but you may quote the fix if you wish and we will consider your company for this service.
