On the submission form, each field can have a different set of validation such as being required, must be an email address format, the number must be greater than 0, etc, etc. These validation restrictions are defined by you when you configure the form. Additionally, you can split your form into multiple pages.
On forms that have multiple pages, the applicant is presented with a Save and Next button that proceeds them to the next page on the form.
You have the opportunity to check to see if the applicant needs to fix any fields at this point, or to wait until they reach the very end of the form when they intend to submit their full application.
To swap between these two settings, first navigate to your program.
Under the Program Settings drop down menu, click Applicant Settings.
Choose which validation method you prefer and click Save.
