Help with pages in search script

This code works, however when you click the next link, it does not redirect, however the $s variable is updated in the URL. Can anyone see where i'm going wrong, apart from no validation yet :)

 

 

<?php

echo '<html>
<body>
<form name="form" action="searchagain.php" method="get">
  <input type="text" name="q" />
  <input type="submit" name="Submit" value="Search" />
</form>
</body>
</html>';

  // Get the search variable from URL
  $var = @$_GET['q'] ;
  $trimmed = trim($var); //trim whitespace from the stored variable

// rows to return
$limit=8;

// check for an empty string and display a message.
if ($trimmed == "")
  {
  echo "<p>Please enter a search...</p>";
  exit;
  }

// check for a search parameter
if (!isset($var))
  {
  echo "<p>We dont seem to have a search parameter!</p>";
  exit;
  }

//connect to your database
mysql_connect("","","");
mysql_select_db("wadkin") or die("Unable to select database"); //select which database we're using

// Build SQL Query  
$query = "select * from books where Title like \"%$trimmed%\"  OR Description like \"%$trimmed%\" OR URL like \"%$trimmed%\"
  order by Title"; 

$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);

// If we have no results

if ($numrows == 0)
  {
  echo "<h4>Results</h4>";
  echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>";
  }

// next determine if s has been passed to script, if not use 0
  if (empty($s)) {
  $s=0;
  }

// get results
  $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

// display what the person searched for
echo "<p>You searched for: "" . $var . ""</p>";

// begin to show results set
echo "Results<br><br>";
$count = 1 + $s ;

// now can display the results returned
  while ($row= mysql_fetch_array($result)) {
  $title = $row["Title"];
  $d = $row["Description"];
  $url = $row["URL"];

  echo "<p>$count) $title<br>$d<br>$url</p>" ;
  $count++ ;
  }

$currPage = (($s/$limit) + 1);

//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print " <a href=\"searchagain.php?s=$prevs&q=$var\"><< 
  Prev 10</a>&nbsp ";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo " <a href=\"searchagain.php?s=$news&q=$var\">Next >></a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
  
  
  

?>
