google map v3, 3 maps on same page

[helenp]

Puf, no veo nada, asi separado me salen dos mapas,
con el mismo nombre de la funcion createmarker me sale solo marcadores en mapa 1,
si cambio el nombre de la funcion createmarker al nombre createmarker2 me sale solo marcadores en mapa 2....

A ver si alguien ve algo mas que se debe de cambiar:
