Hi Krishna,

Let's see here...

1. There's a few ways to do this - you may want to see if you can find someone who knows HTML to help out.
2. I noticed in your other post that you tried using the duration parameter; however this wasn't actually saving the responses already input. You may want to try using javascript to automatically submit the form after a set amount of time.
3. The following link may help provide a bit more light on your question: http://www.empirisoft.com/support/showthread.php?t=409
You could also try using either javascript or an external .exe to accomplish the task.

Let me know if this helps,
Trevor
