How can I request matching input in two different fields in 123FormBuilder?

Sometimes, you may need to request matching input in two form fields; for example, when you ask users to provide and confirm their email addresses.

This type of validation can be easily enabled by following some steps.

Let’s go with the confirmation email address flow. Firstly, you need to add two fields in which the input should be identical.

Confirm email address

For the second field, in our case, Confirm email address, go to Validation on the right-side panel and enable Match another field value. In the dropdown list that appears, select the matching form field, which, in this case, is the Email address field.

Match another field value

By doing this, the pairing is done on both fields. If respondents provide different inputs for the two fields they get an error indicating that the input must be identical. Therefore, they can not submit the form unless the two email addresses are identic.

You can change the text of the message in the Language→ System Messages section (you can search by the word identical to quickly find the system message you want to edit).
