Don Philippo,

try:

<html>
 <head>
  <script language="JavaScript">
   function fnPopulateDateSelect()
   {
    objSelMonths=document.forms.frmSelectDate.selMonths;
    objSelDates=document.forms.frmSelectDate.selDates;
    objSelDates.options.length=0;
    intNumberOfDays=objSelMonths.options
[objSelMonths.selectedIndex].value;

    for (intCounter=0;intCounter<intNumberOfDays;intCounter++)
    {
     document.forms.frmSelectDate.selDates[intCounter] = new Option
(intCounter+1,intCounter+1,false,false);
    }
    objSelDates.focus();
   }
  </script>
 </head>
 <body onload="fnPopulateDateSelect()">
  <form name = "frmSelectDate">
   <select name="selMonths" onchange="fnPopulateDateSelect()">
    <option selected value="31">january</option>
    <option value="29">february</option>
