Enforce completion of required fields before submitting survey

I have a multi-page survey with required fields on each page. I don't want to enforce completing the fields as they go through the pages and was able to figure that out. But, how can I enforce that all required fields be completed before a survey can be submitted?

Please disregard, I figured it out. The form can't be submitted until all required fields are completed page by page.
