Previous question prefill
Sometimes it may be useful to prefill a question with the value of a previous answer. For example, consider a case where you need to collect delivery details as well as contact details. You can use prefills to default the name for delivery to the name entered in the contact details, to prevent the customer entering it twice.
To do this:
In your form, click Advanced > Prefills in the top navigation bar (under the the form title).
Click Add Prefill.
The create interface will open.
Choose the question to prefill e.g. the name for delivery
Choose where the prefill value should come from e.g. the name question on the 'Contact Details' page.
The prefill will be created and added to the list.
