Webform result redirect page

I'd like to do something pretty straightforward: After user fills out a webform, I'd like a button that simply redirects them to a URL (in this case it's to a demo sandbox). of course i want the user to fill in their info to capture for lead-generation purposes. My webform is set up correctly in that it correctly captures all the user fields and submits them to me via email. However, upon completion "click" I'd like to have the user redirected to a determined internal URL www.mysite.com/foo

I can't figure out how this is done with the vanilla webform settings. Am I missing something obvious?

Thanks!
