I don't see any reason that this:

PHP Code:

print_membergroup_row("Title", "recusergroup",2,array('usergroupid' => 0, 'membergroupids' => '1,2,3,4,5,6')); 


would not be the same as this:

PHP Code:

    $groups = '1,2,3,4,5,6';
    print_membergroup_row("Title", "recusergroup",2,array('usergroupid' => 0, 'membergroupids' => $groups)); 


(but you definitely need the quotes around the list).

Also, it looks like there can not be any spaces, so make sure you're not doing this:

PHP Code:

$group = ' 1,2,3,4,5,6 ';
