to get rid of this error:

edit profileplus.module

add this line on line 46: (i.e. just below $users = array();)
$match = array();

the error is coming becuase $match is not defined before using it, so all you ahave to do is define it the way $user is defined.

someone has posted the whole code sippet here too:

all the best!
