Memory fields are a way to store data entered from a previous submission and then populate that field's specific data when a new form instance is started. It is important to note that it will always populate the most recently entered data, which can change each time you fill out the form if you update the field.
Also, memory fields work locally on each device. This means that you will not be able to switch to a different device and still have memory field data from your last submission on your other device. If you wish to have a set value in your field across all devices that does not change, then you will want to use "Default Value."
To enable a memory field, click the memory field button in your desired field's field options panel.
The supported field types for memory fields are:
• Formatted Numeric
• Option List
• Global List
• Lookup List
(if you are populating data with a lookup mapping, it will not work with a memory field)
