Abstract
In this paper we prove that in the classes of all regular frames and all completely regular frames there are universal elements giving an affirmative answer to Problems 1.4 (1, 2) of [1]. To obtain these results we simplify the method of construction of universal elements in the class of all frames given in [1] and then use it for the considered classes.
