The affidavit also “recited that it was based in part on bank records, and it is clear from the context that the portion of the affidavit which set out the amount owed by [Costa and Achecar] was based on bank records.” Taquechel v. Chattahoochee Bank, 260 Ga. 755 , 756 (2) (400 SE2d 8 ) (1991) (citation omitted). An affidavit that refers to bank records to establish the amount owed on a debt must attach those records.

Although the dissent assumes that Felker obtained the knowledge from bank records, Felker neither identified any records as the source of his knowledge nor attached to his affidavit any records addressing the name change or the merger. See Taquechel v. The Chattahoochee Bank, 260 Ga. 755, 756(2), 400 S.E.2d 8 (1991) (finding affidavit insufficient where it was based in part on records that were neither attached to affidavit nor included in record and clearly identified by affidavit). Nor does his affidavit establish a basis for the admission of any such unidentified documents as business records.
