So my members update their courses which is a matrix channel field, tis channel field has 2 cells. Date and course name.
what I would like to do is get the last 3 matrix fields by date across all my members then output the name of the person who updated last.
{exp:channel:entries channel="zoo_visitor" limit="10"}
{member_firstname}{member_lastname}
{courses_completed}
{Date}
{/courses_completed}
{/exp:channel:entries}
