Hi sdgawards,

Thanks for reaching out to Jotform Support. I have tested your form, and it looks like I am unable to recreate this issue. The form can be navigated to next and previous page:

This issue may be temporary, and as precaution, I have also cleared your form's cache.

If this issue occurs on embedded form, can you share with us the webpage URL where the form is embedded, so we can look more to it?

Let us know if you need more help.
