problem with PHP limit page and header("Location:

Hi all,

I am having a problem with a php page im working on.
The page is a results page from a keyword search page.

On this page i limit the records to 10 and have page numbers so the user can click on the page they want records for.

I also have a  script at the top of the page that directs the user back to the search form and echos a message if no fields are filled in and the search is submitted.

The problem i have is if i click one of the page numbers  to view records on that recordset page, the page doesnt load, instead the header code at the top of my page is executed. and i get redirected to the search form as if i just entered a blank search?
I assume this is due to the way i have my code laid out but i am unsure how to fix the issue while retaining my header script at the top of the page.

Here is my entire page code so you can see what i am reffering to.

<?php require_once('Connections/EE_con.php'); ?>
<?php

$keyword_street = "";
$keyword_village = "";
$case = 0;
if(!isset($_REQUEST["keyword_street"]) || $_REQUEST["keyword_street"]=='')
{
      $keyword_street = "<font color=\"red\">Please enter this field!</font>";
}

if(!isset($_REQUEST["keyword_village"]) || $_REQUEST["keyword_village"]=='')
{
      $keyword_village = "<font color=\"red\">Please enter this field!</font>";
}
     
if($keyword_village!="" && $keyword_street!="")
{
      header("Location: keyword2.php?street=$keyword_street&village=$keyword_village");
      // Keyword2.php is the name of the page where my search form is.
     exit();
}
?>

$row_Recordset1 = mysql_fetch_assoc($Recordset1);
