• Confirm An Email Address

  You will need to setup two questions: 

  One question will ask for the email address and add validation as email.

  1. Create question
  2. Make the question a required field
  3. Add validation
  4. Click the down arrow on Minimum length
  5. Select content type
  6. Email address

  

  

  

The second question will be a validation custom type. To get the custom validation you will need to pipe the information from the email question (first question you setup). Copy the piping information into the confirm email address question. (second question you setup)

1. Create the second question: Please confirm the email address
   • Make it required
2. Go back to the question asking for the email address (first question you setup)
3. Check the box and click Piped text tab
4. Pick Survey Question 
5. Find the Question that is asking for an email
6. Click Email address
7. Copy the piping information - It should look like this ${q://QID18/ChoiceTextEntryValue} 
8. Check the second question where you are asking to confirm the email address
9. Add a validation
10. Choose Custom
11. Pick the question for "Confirm the email address"
12. Pick the choice "Please confirm the email address"
13. Pick "Is Equal to"
14. Paste the piping information
15. It is optional to check the "Ignore Case"
16. Load an "email does not match" error message
17. Save

After you have copied the custom validation piping, remember to delete the piping information in the first question as seen in the screenshot above.
