Although denominated a motion to vacate a default, defendants' motion was, in actuality, one to reargue the prior order that had conditionally struck their answer pursuant to CPLR 3126 (3), rendering the instant order nonappealable ( see, Berman v Szpilzinger, 180 AD2d 612). In any event, if we were to review, we would find that defendants provided neither a reasonable excuse for their failure to comply with the conditional order nor an affidavit of merit by one with personal knowledge of the facts ( see, Becerril v Skate Way Roller Rink, 184 AD2d 365, 366).
