Thanks a lot its working, but if i choose only yes, it should redirect to page1.htm.(Its working) but if i choose again No, it should remain in same page.
The page url is /currentpage.php?update=value
How i can do this.?.
<select onChange="my_function(this)">
<option value="" SELECTED>No</option>
<option value="page1.htm">Yes</option>
</select>
Thanks.
