Switch with query only partly works???

Question

I have the following query:
$varSearch_RS_Search = "-1";
if (isset($_GET['Search'])) {
  $varSearch_RS_Search = $_GET['Search'];
mysql_select_db($database_dconn, $dconn);
$query_RS_Search = sprintf("SELECT * FROM products WHERE Category LIKE %s OR products.Manufacturer LIKE %s OR products.Model LIKE %s OR products.Color LIKE %s AND Category!= 'Stage Pianos' AND Category!= 'Recent Pianos' AND Category!= 'Recent Keyboards'", GetSQLValueString("%" . $varSearch_RS_Search . "%", "text"),GetSQLValueString("%" . $varSearch_RS_Search . "%", "text"),GetSQLValueString("%" . $varSearch_RS_Search . "%", "text"),GetSQLValueString("%" . $varSearch_RS_Search . "%", "text"));
switch( $_GET['Sort'] ){
    case '':
        $query_RS_Search .= 'ORDER BY price ASC';
        break;
          case 'Low to High':
        $query_RS_Search .= 'ORDER BYprice ASC';
        break;
    case 'High to Low':
        $query_RS_Search .= 'ORDER BYprice DESC';
        break;
    case 'Color':
        $query_RS_Search .= 'ORDER BY Color ASC';
        break;
    case '0-500':
        $query_RS_Search .= 'AND price BETWEEN 0 AND 500 ORDER BY price ASC';
        break;
          case '500-1000':
        $query_RS_Search .= 'AND price BETWEEN 500 AND 1000 ORDER BY price ASC';
        break;
                    case '1000-2000':
        $query_RS_Search .= 'AND price BETWEEN 1000 AND 2000 ORDER BY price ASC';
        break;
          case '2000':
        $query_RS_Search .= 'AND price BETWEEN 2000 AND 10000 ORDER BY price ASC';
        break;
$query_limit_RS_Search = sprintf("%s LIMIT %d, %d", $query_RS_Search, $startRow_RS_Search, $maxRows_RS_Search);
$RS_Search = mysql_query($query_limit_RS_Search, $dconn) or die(mysql_error());
$row_RS_Search = mysql_fetch_assoc($RS_Search);
The switch works fine for Low to High, High to low and color, however as soon as I try to switch 0-500 it doesn't select the product between 0 and 500 or the other between ranges.
I would like these switches to work as well.
Any help welcome

Answer 1

What I wanted to do was if the $_GET['Sort'] was e.g  0-500 the query would read:
sprintf("SELECT * FROM products WHERE Category LIKE %s OR products.Manufacturer LIKE %s OR products.Model LIKE %s OR products.Color LIKE %s AND Category!= 'Stage Pianos' AND Category!= 'Recent Pianos' AND Category!= 'Recent Keyboards' AND price BETWEEN 0 AND 500 ORDER BY price ASC ect.
Should that be like this?
sprintf("SELECT * FROM products WHERE (Category LIKE %s OR products.Manufacturer LIKE %s OR products.Model LIKE %s OR products.Color LIKE %s AND Category!= 'Stage Pianos' AND Category!= 'Recent Pianos' AND Category!= 'Recent Keyboards)' AND price BETWEEN 0 AND 500 ORDER BY price ASC ect.
