<script>
function addEvent()
{
var ni = document.getElementById('myDiv');
var spant = document.getElementById('span1');

var numi = document.getElementById('theValue');
var num = (document.getElementById("theValue").value -1)+ 2;
numi.value = num;
document.form1.theValue.value = num;
var textIdName = "symptoms"+num;
var newText = document.createElement('TEXTAREA');
newText.cols = 35;
newText.rows = 3;
newText.name = textIdName;
newText.visibility = "visible";


ni.appendChild(newText);
ni.appendChild(document.createElement('BR'));

}
</script>
in html page
<input type="hidden" value="0" id="theValue" name="theValue"/>
 <tr>   
      <td height="22" align="left" valign="top" class="style5"><font face="Arial, Helvetica, sans-serif">dynamic textboxes</font></td>

try this .......it may help
write this in the head part........

<script language="javascript">
function changeIt()
{
var i = 1;
my_div.innerHTML = my_div.innerHTML +"<br><input type='text' name='mytext'+ i>"

}
</script>

and write this in the body.........

<form name="form" action="post" method="">
<input type="text" name=t1>
<input type="button" value="test" onClick="changeIt()">
<div id="my_div"></div>

with this code whenever you'll click the button a new textbox will appear.
