Ok.
Place the two radio buttons on your form. Call them, in example, "url" . Now, right click the first and paste the following code in the Inside Tag of it's html:
onclick="changeaction
1()"
Repeat for the second one, but the code should be:
onclick="changeaction2()"
Now, copy the following code and paste it in the Inside Head Tag of the Page HTML:
<script language="JavaScript" type="text/javascript">
function changeaction1()
{
document.forms[0].action = 'http://www.dbtechnosystems.com' ;
}
function changeaction2()
{
document.forms[0].action = 'http://www.navaldesign.info' ;
}
</script>
You can see, in red, the URLs that i have used in this example, replace them with your own. If you have more than two radio buttons, add code accordingly.
