Combo cuadruple

[gamuba]

Buenas tardes, saque el siguiente codigo para combo doble de un codigo ya fabricado y le añadi otros dos. El tercero funciona perfectamente pero el cuarto no hace nada. Estoy empezando en esto y estoy bastante perdido.


el codigo es este:

var groups=document.isc.stage.options.length
var group=new Array(groups)
for (i=0; i<groups; i++)
group[i]=new Array()


group[0][0]=new Option("Fecha de nacimiento"," ");
