<?php
mysql_free_result($rsMarca);
mysql_free_result($rsColeccion);
?> espero que veas alguna solucion porque yo no se como seguir.
pd: creo que con ajax no puedo hacerlo, porque implicaria que en la lista 1 me salgan todos los registros de la tabla categorias (saldrian marcas repetidas y no funcionaria bien ya que usa los id de cada campo)
