var n1 = parseInt(document.dosificacion.capacidad.value);

alert('Ingresa la capacidad');
return;

var n5 = parseInt(document.dosificacion.dosificacion.value);
var esencia = (n1 * n5/100).toFixed();
var n2 = parseInt(esencia);
var n6 =("0.08");
var fijador = (n1*n6).toFixed();
var perfumol = (n1 - n2 - fijador).toFixed();
document.dosificacion.esencia.value = esencia + " g.";
document.dosificacion.fijador.value = fijador + " g.";
document.dosificacion.perfumol.value = perfumol + " g.";
