How to remove %20 from the link parameter value of a vertical sprymenubar?

Question

I have a Vertical menubar but I want to link the menu's to a new page where I sent a parameter value acros.
The url displays:
http://localhost/Category.php?Category=Digital%20Piano
I want it to display the following:
http://localhost/Category.php?Category=Digital-Piano
This is what the menu looks like
<ul id="MenuBar2" class="MenuBarVertical">
        <li><a class="MenuBarItemSubmenu" href="Category.php?Category=Digital Piano">Digital Pianos</a>
          <ul>
            <li><a href="#">All digital pianos</a></li>
I have tried to use str_replace, however that didn't work
Also I want to echo out the url without the "-" on the main page
Like so <?php echo $_GET['Category']; ?> where it diplays Digital piano rather than Digital-Piano
I presume I have to encode the Category=Digital Piano, however I have no idea where to start

Thanks for your quick response.
I actually tried that, but when I do it won't search my database as in there the Digital Piano is without a space.
The menubar is as follows:
<ul id="MenuBar2" class="MenuBarVertical">
        <li><a class="MenuBarItemSubmenu" href="Category.php?Category=Digital Piano">Digital Pianos</a>
          <ul>
            <li><a href="#">All digital pianos</a></li>
            <li><a href="#">Casio Digital Pianos</a></li>
            <li><a href="#">Kawai Digital Piano</a></li>
            <li><a href="#">Korg Digital Pianos</a></li>
            <li><a href="#">Roland Digital Pianos</a></li>
            <li><a href="#" class="MenuBarItemSubmenu">Yamaha Digital Pianos</a>
              <ul>
                <li><a href="#">Yamaha Clavinova</a></li>
                <li><a href="#">Yamaha Digital Pianos</a></li>
              </ul>
            </li>
            <li><a href="#">Pre-Owned Digital Pianos</a></li>
            <li><a href="#">Other Digital Pianos</a></li>
          </ul>
        </li>
        <li><a href="#">Pre-Owned Digital Pianos</a></li>
        <li><a href="#" class="MenuBarItemSubmenu">Keyboards</a>
          <ul>
            <li><a href="#">All Keyboards</a></li>
            <li><a href="#">Casio Keyboards</a></li>
            <li><a href="#">Ketron Keyboards</a></li>
            <li><a href="#">Korg Keyboards</a></li>
            <li><a href="#">Roland Keyboards</a></li>
            <li><a href="#">Yamaha Keyboards</a></li>
            <li><a href="#">Pre-Owned Keyboards</a></li>
            <li><a href="#">Other Keyboards</a></li>
          </ul>
        </li>
        <li><a href="#">Pre-Owned Keyboards</a></li>
        <li><a href="#">Recording</a>        </li>
        <li><a href="#">Amplilication</a></li>
        <li><a href="#">Accessories</a></li>
        <li><a href="#">Modules & Add-On's</a></li>
      </ul>
    </div>
All the other Piano and keyboards will get a link as well, but what I was hoping to do was not make a seperate page for each category
But just use the link
the recieving page looks as follows:
  $maxRows_getResults = 7;
$pageNum_getResults = 0;
if (isset($_GET['pageNum_getResults'])) {
  $pageNum_getResults = $_GET['pageNum_getResults'];
$startRow_getResults = $pageNum_getResults * $maxRows_getResults;
$varCategory_getResults = "-1";
if (isset($_GET['Category'])) {
  $varCategory_getResults = $_GET['Category'];
mysql_select_db($database_dBconn, $dBconn);
$query_getResults = sprintf("SELECT * FROM products WHERE Category LIKE %s", GetSQLValueString("%" . $varCategory_getResults . "%", "text"));
switch( $_GET['Sort'] ){
    case 'Low to High':
        $query_getResults .= 'ORDER BY Keysound_price ASC';
        break;
    case 'High to Low':
        $query_getResults .= 'ORDER BY Keysound_price DESC';
        break;
    case 'Color':
        $query_getResults .= 'ORDER BY Color ASC';
        break;
    case '0-500':
        $query_getResults .= ' AND products.Keysound_price BETWEEN 0 AND 500 ORDER BY Keysound_price ASC';
        break;
          case '500-1000':
        $query_getResults .= ' AND products.Keysound_price BETWEEN 500 AND 1000 ORDER BY Keysound_price ASC';
        break;
                    case '1000-2000':
        $query_getResults .= ' AND products.Keysound_price BETWEEN 1000 AND 2000 ORDER BY Keysound_price ASC';
        break;
          case '2000':
        $query_getResults .= ' AND products.Keysound_price BETWEEN 2000 AND 10000 ORDER BY Keysound_price ASC';
        break;
$query_limit_getResults = sprintf("%s LIMIT %d, %d", $query_getResults, $startRow_getResults, $maxRows_getResults);
$getResults = mysql_query($query_limit_getResults, $dBconn) or die(mysql_error());
$row_getResults = mysql_fetch_assoc($getResults);
if (isset($_GET['totalRows_getResults'])) {
  $totalRows_getResults = $_GET['totalRows_getResults'];
} else {
  $all_getResults = mysql_query($query_getResults);
  $totalRows_getResults = mysql_num_rows($all_getResults);
$totalPages_getResults = ceil($totalRows_getResults/$maxRows_getResults)-1;
$queryString_getResults = "";
if (!empty($_SERVER['QUERY_STRING'])) {
  $params = explode("&", $_SERVER['QUERY_STRING']);
  $newParams = array();
  foreach ($params as $param) {
    if (stristr($param, "pageNum_getResults") == false &&
        stristr($param, "totalRows_getResults") == false) {
      array_push($newParams, $param);
  if (count($newParams) != 0) {
    $queryString_getResults = "&" . htmlentities(implode("&", $newParams));
$queryString_getResults = sprintf("&totalRows_getResults=%d%s", $totalRows_getResults, $queryString_getResults);
On the main page I use the <?php echo $_GET['Category']; ?> to echo out the category name
Hope this helps
