Debug a custom php script

I have a script that fetch data from real estate classifieds site. That script was working fine last time i used it. Now, it isn't working anymore. The script have been well written by a good coder and it runs on my vps. But original coder is busy now and i'm in hurry. I need a php ninja to debug and fix it. This will be a quick shot, probably less than an hour. And if you perform well, we will work together because i want to expand the script. Here arethe strict requirements : 1 - you should be directly the coder, no agency, no intermediate, and i'll spot you. 2 - You should be available this wenesday 3 - you should be good php coder, i don't want to waist time And if you lie me on any of these points, i won't pay u, just because u lied me. Here is attached the file of one of main project script so u can have an idea. To be sure you are interested, start your message by telling me the last word on line 684
