I am trying to output from mysql database, the code i have, which is just before the opening html tag, is this below

 

<?php include('connecting_file.php');
$catid=$_GET['cat'];
$subid=$_GET['subcat'];
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

mysql_select_db($database_name, $pmo);
$query_cat = "select * from subcat where catid='$catid'and subid='$subid'";
$cat = mysql_query($query_cat, $pmo) or die(mysql_error());
$row_cat = mysql_fetch_assoc($cat);
$totalRows_cat = mysql_num_rows($cat);
?>

 

Then i use this one to output the content from the table by just adding this code to where i want content to appear

<?php echo $row_cat['content']; ?>

 

but all i get is

Notice: Undefined index: cat in C:\wamp\www\mysite\aboutus.php on line 2

Notice: Undefined index: subcat in C:\wamp\www\mysite\aboutus.php on line 3

 

Can someone please help me out
