The last section to personalize in your Survey that is visible on the survey is the Form Submit section. The main function of the Form Submit section is the SUBMIT button.
By default on a Survey the Section Heading is left blank. This way the flow of the form goes right from the last entry of the survey, whether it is questions or contact information directly to the button to submit the answers.
If you want to separate the button further you can include a header of some sort.
You have 14 characters to create the button to submit the details of the form. If the default "Submit" is too generic for you, you can change it to fit the theme of your Activity or just make it more personal.
This is used for fraud protection on a payment form, such as a Text to Donate or a Ticketing activity. It is still available on non-payment forms such as the Survey, just in case you want an extra layer of security. For example, if your organizations goals may be considered controversial, you make have people try to "spam" your survey making it more difficult to review the real submissions from the fakes.
Disabled by default, you can enable Re-Captcha to include the "I am not a Robot" box on the form. The supporter would need to click on the box to get a green checkmark before it would allow them to Submit the form. This is one method to counter "bots" that may try to automatically fill out your forms.
Confirm before submitting
This is also used for additional fraud protection. When the supporter clicks the Submit button, it will pop up a message to confirm if they want to complete this transaction. For a real person, this can just be a nice "last chance" message to make sure they have everything correct before submitting their answers, but for the automatic bots used to spam or commit fraud, this pop up can break their routines.
