Writing a birthday calendar with a multiset of birthday objects but sorting isn't working

I am writing a birthday calendar with a multiset of birthday objects. My comparison function isn't sorting right and I can't search for a b-day by name.

class CompareName
    {
    public:
        bool operator()(Birthday* a,Birthday *b)
        {
            if(a->getLastName()==b->getLastName() && a->getFirstName() != b->getFirstName())
                return( a->getFirstName() < b->getFirstName());
            else
                return (a->getLastName()<b->getLastName());
        }

This is my comparison function. I am wanting to be able to search the database by birthday or partial birthday and whole name. I cant get the search by name part working.

    void MultiSet::searchByName( Birthday *a)
{
    NameSet::iterator result;

    result=nameSet.find(a);


    if(result!=nameSet.end())
        (*result)->print();
}

I have already used a type def for the multiset and have used it in my definition to include the object functor, but have left it out of this code excerpt for brevity.

Where is `CompareName` used? – Nick May 09 '13 at 19:34
typedef multisetNameSet; – AlexGimson May 09 '13 at 19:35
and what does getLastName(), getFirstName() return? – Nick May 09 '13 at 19:41
The logic in your comparison seems correct, I would suggest putting up a http://sscce.org/ so that others may look at your entire code for errors. – Chad May 09 '13 at 20:19
