I have been trying to figure out why if $currentpage is greater than 2 then the variable $strZipCode will pass empty?

 

<?php 
$range=4;
// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {

   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) { 
         // 'highlight' it but don't make a link
         echo " [<b >$x</b>] ";
      // if not current page...
  
      }

  else {
         // make it a link http_build_query( $strName,$strZipCode, $strState, $arrFoodTypes, $arrOfferings)
         echo  " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x&strZipCode= ". $strZipCode . "'>$x</a> ";
      } // end else
   
   } // end if 

} 
?>
