On August 1, 1987, Dori Leeds signed a “guarantee of credit” with Sun Control Systems, which guaranteed “the prompt payment, when due, of every claim of [Sun Control Systems] against [Dori Leeds dba ‘Blind Ambitions’].” At the time she signed the guarantee of credit, Blind Ambitions was in the business of installing window treatments and installed only Faber brand blinds, which were purchased from Sun Control Systems. In 1991, Sun Control Systems sold and assigned all of its assets to Faber. Shortly thereafter, Dori assigned her interest in Blind Ambitions to David and Judith Leeds, who continued to do business as Blind Ambitions. In 1994 and 1995, Blind Ambitions made credit purchases from Faber and did not pay under the terms of those contracts. Faber brought suit against Dori Leeds as the guarantor of credit for Blind Ambitions. Dori refused to pay on the grounds that she was acting as a personal guarantor for her business, not for Blind Ambitions. Is she correct?
