ok i want to make it using the php that you gave me, i have tried it but it doesnt seem to be working
this is what i have:
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($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;
$var1_Recordset1 = "-1";
if (isset($_GET['CatID'])) {
  $var1_Recordset1 = $_GET['CatID'];
mysql_select_db($database_beau, $beau);
$query_Recordset1 = "SELECT * FROM beaProdSizes, beauCat WHERE beaProdSizes.CatID = beauCat.catID";
if (isset($_GET['catID']) && is_numeric($_GET['catID'])) {
    $query_Recordset1 .= ' AND beauCat.catID = ' . $_GET['catID'];
$Recordset1 = mysql_query($query_Recordset1, $beau) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
?>
<div class="header" id="beauTitleBOX"><?php echo $row_Recordset1['catname']; ?></div>
        <div id="beauSelectBOX">
          <form id="FormName" action="" method="get" name="FormName">
            <select id="selectName" name="name">
              <option value="Select Design">Select Design</option>
              <?php
do {
?>
              <option value="<?php echo $row_Recordset1['catID']; ?>"><?php echo $row_Recordset1['name']; ?></option>
              <?php
} while ($row_Recordset1 = mysql_fetch_assoc($Recordset1));
  $rows = mysql_num_rows($Recordset1);
  if($rows > 0) {
      mysql_data_seek($Recordset1, 0);
            $row_Recordset1 = mysql_fetch_assoc($Recordset1);
?>
            </select>
            <input type="submit" name="button" id="button" value="select" />
          </form>
        </div>
        <div class="header" id="beauPrice"><?php echo $row_Recordset1['price']; ?></div>
        <div class="text" id="beauOtherContent"><?php echo $row_Recordset1['desc']; ?></div>
