If your form has an approval route, you can choose whether or not approvers will be able to edit information filled out by those prior to them in the route. Note: Even if fields are marked as "Editable by approvers," each approver must have also been given editing rights during the form setup process in order to be able to edit those fields.
- Click on the field to open the grey field settings box
- Click on the "Editable by approvers" checkbox at the bottom to enable edits
