How to add a button at end of a survey to go to an external URL? - by: saputera

Hello,

Does anyone know how to add a button at the end of a survey in order to go to an external URL?

I'm trying to change the source code, but was wondering if anyone has done this before.

Basically I'd like to add a "Preview" button next to "Submit" button at the last page of survey, such that when it's clicked, participants will be redirected to an external link (which will show the preview of current survey results in some format that we desire).

Thanks,
Anna
