I don't know how you have defined you function....but It looks like if your function doesn't get anything like argument I can't see the logic of adding two points...and a lvalue is a place to hold the information....as you are assigning you should provide somewhere to keep that information...

thanx for the reply i got it to work by passing my get function by reference

 
// player points
    void setPoints(int );
    int &getPoints();
