Depending on the record type you are searching for, the steps below should allow you to sort your records by Contact's last name rather than first name:
1. After pulling your search in the GIFTS Online workspace, click the Folder icon at the bottom center of your screen to open up your Views
2. The Change Display window now opens > Under 'Select available columns from', choose 'Contacts'
3. Under the Available Columns, there should be a Contact: Name (Last, First) option > Highlight this column and click 'Include>' to add the column to your View
4. Click 'Apply'
5. Your View should now have a column with the Last Name, First Name display for your contacts.
