   Código PHP:
   
    <?php
        require_once("conexion/conexion.php");
        $id = $_GET['id'];
        $sql="SELECT DISTINCT ".$_GET['id']." FROM julio";
        $res=mysql_query($sql,$con);
    ?>
            
       <select id="combobox">
       <option value"0" selected="selected"></option>
     <?php   
        //echo "$id";
        while ($reg=mysql_fetch_array($res))
        {
            echo"<option value='$reg[$id]'>$reg[$id]</option>";
        }
    ?>
        </select>   tengo el firebug y pues viendo el codigo si me manda el select lleno con los datos ue necesito pero el autocomplete no me funciona y cuando pongo manualmente la libreria de jquery con el firebug si sirve perfectamente el autocomplete
