Page Separation Problem

[quantum_leap]

Hi, to everyone, this is my first post in the forum. I am a designer with very basic understanding of PHP. I have designed a website for a real estate agency that I am running. I have passed over the design to a local company and they have provided me with an offline software solution where I keep all records of clients and properties with the software being able to update the website records as well, through PHP and MySQL. Their support has been dreadful to say the least, basically they have left me helpless trying to solve issues myself. One issue I am trying to solve is on the results page. The search property form calls a search_results.php page that includes a page_separation.inc file inside the code. I believe that file is the source of the problem. All results are displayed correctly, 10 results in a row. I can recognize the code inside page_separation.inc where this is happening. The problem is that when I click on the next button instead of displaying the next 10 results, it displays all available properties in the particular area/city they user is searching, rendering results confusing for users. I believe the source of evil is in that page_separation.inc file at the point where it renders the url, something is going wrong there. So I am posting the contents of the code in case someone can have a look and help me, if it's possible. Thank you!
