buenas txane,

me he instalado eso, pero realmente no se que tengo que hacer para hacerlo funcionar.

aqui os posteo todo el codigo del form. creo que ahi debe de estar el error, ya que al tocar la segunda select se me dispara el submit del form.

Código:

<form name="form1" method="get" action="resultados_busqueda.php">
        <font face="Verdana, Arial, Helvetica, sans-serif"><strong><font size="1" face="Verdana, Arial, Helvetica, sans-serif"><font face="Verdana, Arial, Helvetica, sans-serif"><strong><font size="1" face="Verdana, Arial, Helvetica, sans-serif"><span class="fila"><span class="cajasTextoCursos Estilo28"><font face="Verdana, Arial, Helvetica, sans-serif"><strong><font face="Verdana, Arial, Helvetica, sans-serif">Buscador de ofertas</font><br>
        </strong></font></span>
        <select name="canal" class="selectsFormacion" id="select2" onChange="window.open('?canal=' + escape(document.form1.canal.value) + '&provincia=' + escape(document.form1.provincia.value)  + '&idcandidato=' + <? echo $userArray["idcandidato"];?> , '_self')">
            <option value="">--Seleccione una Opcion--</option>
            <? 
		include("conexion.php");
		
		
       $query_bd= mysql_query("SELECT DISTINCT canal FROM categorias ") or die (mysql_error());
while ($rows=mysql_fetch_assoc($query_bd))
    {       
    if ($canal==$rows['canal'])
         { ?>
            <option  value="<?=$rows['canal']?>"  selected="selected">
            <?=$rows['canal']?>
            </option>
            <? }
          else
               {?>
            <option  value="<?=$rows['canal']?>">
            <?=$rows['canal']?>
            </option>
            <? }?>
            <? } ?>
