Activar Desactivar / No Anda En Ratio Button

[daenor]

Muy buenas tardes!!!

Bien, me gustaria saber si pueden ayudarme respecto a lo siguiente.
Estoy utilizando una funcion que se activa con un select, cual es la siguiente:

Código PHP:

  <script>
function activar(Tipoprog){
 
if(document.formularioCARGA.Tipoprog.value=='Trigger'){
        document.formularioCARGA.INSERTX.disabled=!document.formularioCARGA.INSERTX.disabled;
        document.formularioCARGA.StoreProcedure1.disabled=!document.formularioCARGA.StoreProcedure1.disabled;
        document.formularioCARGA.afterbefore.disabled=!document.formularioCARGA.afterbefore.disabled;
}else{
}
}
</script> 
  

y el form

Código PHP:

  <form name='formularioCARGA' action='/pbusers/generar.php?accion=grabartarea&data=segunda' method='post'>
&nbsp;
<input type='hidden' name='Nombre2' id='Nombre2' value='ARIEL ALE'/>

pERO ME sucede que cuando activo el "trigger" los campos de ratio no se activan. Como es posible hacer que eso suceda?

Atte.
Muchisimas gracias desde ya!
