on the same page, a hidden textarea will show up, if user select No,
then nothing happen.

on the response.write line
anyone has idea, please help me out, I would really appreciate your

<form name="form1" method="post" action="test13.asp">

<select name="test">
<option value=""></option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>

<%strtest = request("test")%>
<%
If strtest = "Yes" Then
response.write "<textarea name="whatis" cols="50"></textarea>"
Else

End if
%>

</form>

ASP is server side technology. What you want is client-side script, like
javascript or client-side vb script. The best way to handle it is to put
the textbox inside a hidden <div> tag, then in the OnChange event for the
select box, check for the value you want and un-hide the div. Like so:

<form name="form1" method="post" action="test13.asp">

<select name="test" onChange="if (document.form1.test.options[1].selected)
{document.hiddenDiv.style.display=''} else
{document.hiddenDiv.style.display='none'} ">
<option value=""></option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>

<div style="display: none" name="hiddenDiv">
<textarea name="whatis" cols="50"></textarea>
</div>

You might want to address any further questions like this to a client-size
scripting group.
