Deluge script - set destination page of a form

In Zoho Sites, I have created a form on the Forms tab. The form works great. What I need now it to tell the form to open another page at the site when the user clicks the submit button. (I know how to do this with a webform, but I am not using a webform.)

I selected the button and clicked Configure on-click actions. I know the answer is here and it's probably quite simple, but I don't have much experience with Deluge script. Can someone tell me how to set a destination page of the form, please?

Thanks,
