Help multi-step form slider

Hello, I’d like to improve this multi-step form. I made each of the form slides (six total) required, however, I want it so the user can’t go to the next step without filling out the last. It might end up with errors if the user does not fill it out correctly. The form was initially a template that I edited and some of the steps are checkboxes instead of radio buttons, is there a quick way to change this?

Thanks in advance.
