La verdad es que estoy aprendiendo PHP y no se ya que hacer. Si lo ejecutas, solo falla los campos de Firstname, Lastname, Yourgender. Los campos de password y el texto que hay debajo de Membership Form si funcionan. Sale resaltados de color si no rellenan.
Y si rellenas todos los campos si se envía el formulario.
Osea el fallo esta en: Firstname, Lastname, Yourgender. Debe ser que el codigo esta mal construido. Algo que no se, seguro. Os dejo el script a ver si me podeis ayudar:
