var alive1 = new Array("Yes","No");
var alive2 = new Array("");
var loss = new Array("");
var dead = new Array("");
function set_ycontact(){
  var select_status= document.form1.status;
  var select_ycontact= document.form1.ycontact;
  var selected_status= select_status.options[select_status.selectedIndex].value;
  select_ycontact.options.length=0;
  if (selected_status == "alive1"){
    for(var i=0; i < alive1.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(alive1[i],alive1[i]);
  }
  if (selected_status == "alive2"){
    for(var i=0; i < alive2.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(alive2[i],alive2[i]);
  }
  if (selected_status == "loss"){
    for(var i=0; i < loss.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(loss[i],loss[i]);
  }
  if (selected_status == "dead"){
    for(var i=0; i < dead.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(dead[i],dead[i]);
  }
}
var alive1 = new Array("Yes","No");
var alive2 = new Array("");
var loss = new Array("");
var dead = new Array("");
function set_ycontact(){
  var select_status= document.form1.status;
  var select_ycontact= document.form1.ycontact;
  var selected_status= select_status.options[select_status.selectedIndex].value;
  select_ycontact.options.length=0;
  if (selected_status == "alive1"){
    for(var i=0; i < alive1.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(alive1[i],alive1[i]);
  }
  if (selected_status == "alive2"){
    for(var i=0; i < alive2.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(alive2[i],alive2[i]);
  }
  if (selected_status == "loss"){
    for(var i=0; i < loss.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(loss[i],loss[i]);
  }
  if (selected_status == "dead"){
    for(var i=0; i < dead.length; i++)
   select_ycontact.options[select_ycontact.options.length] = new Option(dead[i],dead[i]);
  }
}

the corresponding php script is :

<td width="21%" class="invisible">Patients Status </td>
 
		<select name="status" id="status" tabindex="6" onChange="set_ycontact();">

First, if you have Register Globals = Off in your php.ini (which is recommended), than you have to extract your $status variable from your post data, with a line like:
$status = $_POST['status']; (or $_GET['status'], if your form uses the Get method)
Second, change the Body tag of your html to:
<body onLoad="set_ycontact();">
so you trigger the form fields update on page load.

That's all
