Redirect to a specific URL after submission based on conditions.

If the last question of the form is a YES or NO question, can the person select yes and be redirected back into the form sequence?

For example: a person selects yes at the end on this form, i would like it to redirect them to the Alight, Let's get Specific question which is question number 4 on this form:

https://form.jotform.com/80444046958160

I have any conditions on this form, would redirecting a person back in the sequence mess up any of the condition I have set up on this form?

not a specific url but a specific question on the form

I see, so you want the user to be redirected from the last page to a page located at the beginning or middle of the form? Unfortunately, that is not possible. As you may already know, it is only possible to show fields based on users answers on previous fields.
