Hey @bluesguitarmaster,
You only need to put in one URL in the “On Submit” field, but that URL will change based on the field the user selects from the form. It will look something like this: http://bluesguitarmaster.com/thank-you/%EXPERIENCE_LEVEL%/ (I noticed you have both experience level and skill level, you should make this just one).
If a user selects “beginner” they will be redirected to http://bluesguitarmaster.com/thank-you/Beginner/ if they select “Intermediate” they will be redirected to http://bluesguitarmaster.com/thank-you/Intermediate/. You will need to build a thank-you page for each option in the drop down unless you use a query parameter and javascript to customize the landing page.
The personalization tag, is being replaced with the field they just populated. This is the same as if you sent an email, you would use a personalization tag like
“Hey %FIRST_NAME%, Thank you for…”
You can use this form I created to test this out: Please verify yourself to continue...
