Why do I get a 'Repositioning the page here will break the existing logics' error while I am designing the form?

Why do I get a 'Repositioning the page here will break the existing logics' error while I am designing the form?

You will encounter this error when you try to reposition the pages that include the conditional formula field in such a way that the conditional formula is placed above the fields involved in its configuration. Since, the condition is checked based on the answers of the form fields in the page, we restrict this action as it breaks the logic.
