PHP - A Weird While Loop Problem !

Hello there,

I am making a function to execute every time with a new demand no. in the while loop below. Every thing goes fine for the first time when the page loads, all the taxes come perfectly and each record is being read with the function calculateTaxes($demandno). But, when I press the search button with blank entries... All the entries come with only the first record. Means, the calculateTaxes function is not being loaded again and again with the loop when the press the search button.

Please help.

Please have a look in the below given code:

Code: [Select]
<?php
function renderform($wardno, $demandno, $name)
{
include_once $_SERVER['DOCUMENT_ROOT'].'/npms/header.php';
include_once $_SERVER['DOCUMENT_ROOT'].'/npms/config/config.php';
include_once $_SERVER['DOCUMENT_ROOT'].'/npms/functions/functions.php';
include_once $_SERVER['DOCUMENT_ROOT'].'/npms/functions/connect-db.php';
extract($GLOBALS);

if ($demandno == '' && $wardno == '' && $name == '') // all empty.
{
$result = mysql_query("SELECT * FROM sform where paid=false order by wardno, id, demandno limit 0,$maxrecords") or die(mysql_error());
}
if ($demandno != '' && $wardno != '' && $name != '') // all full.
{
$result = mysql_query("SELECT * FROM sform where demandno='$demandno' and wardno='$wardno' and (name like '%$name%') and paid=false order by wardno, id, demandno") or die(mysql_error());
