I get a blank page when I use data assist

I have used DA in the past and it's worked fine. Now I am using a very simple search for landlords and/or gender and all I see when I try is a blank page. Before applying Data Assist I could see a list as expected but now even accessing the results page directly shows nothing but I can't see what is stopping the page displaying. Any help gratefully received. (I have attached the two pages.)

a blank page means that a php error is occurring but error reporting is turned off.

to turn error reporting on, add the following code at line 1:

<?php

error_reporting(E_ALL);

ini_set('display_errors','on');

?>

once we know what the error is, we will be able to troubleshoot the cause.

Thank you. I have done that and got:

Deprecated: mysql_pconnect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /Applications/MAMP/htdocs/acc3/Connections/blac.php on line 9

Fatal error: Call to undefined function setQueryBuilderSource() in /Applications/MAMP/htdocs/acc3/cms/admin/search_advice_results.php on line 57

move this line:

<?php
//WA Database Search Include
require_once("../../WADbSearch/HelperPHP.php");
?>

to line 1.

Thank you. I now see a listing but if I apply the search it doesn't do any filtering at all - all of the data is listed and I see at the top of the page:

Notice: Undefined variable: WADbSearch1 in /Applications/MAMP/htdocs/acc3/cms/admin/search_advice_results.php on line 62

Notice: Trying to get property of non-object in /Applications/MAMP/htdocs/acc3/WADbSearch/HelperPHP.php on line 381

I'll need to troubleshoot directly, see the private message section.
