Highlight a text field when respective radio button is clicked

[sreeharshakakar]

Hie..I am working asp page with java script as script language. In a form, I have two radio buttons stating active or inactive. I have two text fields next to radio buttons containing Date activated and Date released (for inactive)
Now , I want the text field to be highlighted only when user selects respective button.
Eg.. If user selects active, I want Date activated text field to be highlighted automatically and if user selects inactive, Date released text field must be highlighted
This is a part of my code containing radio buttons with normal textfields date activated and date released

<%@ LANGUAGE="JAVAS CRIPT" %>
<!-- #include virtual="/header.asp" -->
<%
/**
* file: application/inventory/add.asp
* description: allow users to add a new vehicle to the DB
**/
%>
<script language="javas cript">

</script>
<%

// the form
Response.Write( "<form action='add.asp ' method='POST' onsubmit='retur n checkForm()' name='myform'>" );


// Radio button control
Response.Write( "<tr class='d0'><td> Status</strong></td><td>Active: <input type='radio' name='status' value='1' />&nbsp; &nbsp; Inactive: <input type='radio' name='status' value='0' /></td><tr>");
Response.Write( "<tr class='d0'><td> Date Activated</strong></td><td><input name='Dateactiv ated' type='text' /></td></tr>");
Response.Write( "<tr class='d0'><td> Date Released</strong></td><td><input name='Daterelea sed' type='text' /></td></tr>");

Response.Write( "<input type='submit' value='Submit' />");
Response.Write( "<input type='reset' value='Reset' />");
Response.Write( "<input type='button' value='Cancel' onclick='window .location=\"sea rch.asp\"' />");
Response.Write( "</form");
%>

<!-- #include virtual="/footer.asp" -->

I really appreciate your help...:)
