calendario javascript

[joshenema]

muy buenas, a ver si alguien me puede ayudar:
Tengo este codigo para un calendario. Lo que quiero conseguir es que cuando pulse el boton del calendario, me muestre automaticamente el dia actual, ya que si se escribe por ejemplo cualquier numero suelto, muestra el año 1900. Le he dado mil vueltas pero no consigue arreglarlo.

Lo corto en 2 trozos, ya que no me cabe en el post.

Espero me podais ayudar

Gracias

Hola joshenema, te consulto para saber si te paso lo mismo, te comento que estoy utilizando el mismo calendario pero en firefox al visualizarlo me aparece en la parte inferior izquierda (en internet explorer no pasa eso), sabes a que puede deberse???
Gracias...
