Default Dependent Dropdown php/mysql/java

Hi,

Im kinda new to php/mysql programming and I was hoping I could get some help with this. I am trying to create 2 dependent dropdown menus. gThe first one dictate the content of the second one. I hot the connection right but once the second menu loads I could scroll down the list but nothing it is showing on it. ike i cant see the fonts. I read the page source and it is showing the options on it.
Any help I would greatly appreciate.

Here it is the code:
$category = $item = null; //declare vars

$conn = mysql_connect($server,$user,"");
$db = mysql_select_db('sin',$conn);

if(isset($_GET["category"]) && is_numeric($_GET["category"]))
{
    $category = $_GET["category"];
}

if(isset($_GET["item"]) && is_numeric($_GET["item"]))
{
    $item = $_GET["item"];
}
?>

<script language="JavaScript">

function autoSubmit()
{
    var formObject = document.forms['theForm'];
    formObject.submit();
}

</script>

<form name="theForm" method="get">

    <p>

  </p>
    <table width="200" border="1">
      <tr>
        <td>Select Category</td>
      </tr>
      <tr>
        <td><select name="category" onchange="autoSubmit();">
          <option value="null"></option>
          <option value="199" <?php if($category == 199) echo " selected"; ?>>Hydraulics</option>
          <option value="299" <?php if($category == 299) echo " selected"; ?>>Electronics</option>
        </select></td>
      </tr>
      <tr>
        <td>Select Item</td>
      </tr>
      <tr>
        <td>
          <div align="center" class="style2 style3">
            <select name="item" onchange="autoSubmit();">
              <option value="1">select Here</option>
              <?php

        //POPULATE DROP DOWN MENU WITH COUNTRIES FROM A GIVEN REGION

        $sql = "SELECT cat, desc_p FROM parts WHERE cat <= $category";
        $items = mysql_query($sql,$conn);

        while($row = mysql_fetch_array($items))
        {
            echo ("<option value=\"$row[desc_p]\" " . ($item == $row["desc_p"] ? " selected" : "") . ">$row[dec_p]</option>");
        }

        ?>
            </select>
          </div></td>
      </tr>
    </table>
    <p><br>
    </p>
</form>
