Redirecting form based upon selection

I have a question.... I have a form that based upon the answer to a couple of questions will show one of two submit buttons and will either just submit the form or will take them to another form to pay.

My question is I have the conditions set up but do I put anything in the Thank You page?  Do I set it to redirect to URL or just leave it at show thank you page.  I was confused since I would be directing the user to different thank you pages based upon answers so I didn't think I should put anything (but select direct to URL)???  

I am very confused with this.  Please advise

If I'm understanding your concern correctly, I believe you would not be needing to have 2 submit buttons in your form. What you need are conditions that will redirect your respondents to different external pages based on the selections they made on your form. To better understand how you can create such conditions, please refer to this guide — Redirecting-Users-to-a-Different-Page

I have the conditions on the form already.

Since I only want to redirect when this condition is met, then what would I put in the Thank You Page (redirect to URL or show Thank You Page) to ensure that if this condition is met it goes to this URL and if it is not met then it goes to the Thank You Page?

To be able to to do that, the condition should be as you created.

When it is true, a user is redirected to that other form, when it is not true, a Thank you page is shown.

Let us know if you have any further questions.

Thank you!
