Moving a method

I am trying to move this method from one cpp file to another, but when I do I am getting all kinds of errors, could someone show me the proper way to move the method "amountFor". This is not homework, I am doing it from a book but the book is in Java.

Customer.cpp

void Customer::amountFor(Rental & aRental, double & thisAmount)
{
    switch (aRental.getMovie().getPriceCode()){
        case Movie::REGULAR:
            thisAmount += 2;
            if(aRental.getDaysRented() > 2)
                thisAmount += (aRental.getDaysRented() - 2) * 1.5;

            break;

            break;
    }
}

string Customer::statement()
{
  double totalAmount          = 0;
  int    frequentRenterPoints = 0;

  // Init result string
  string result("Rental Record for ");
  result += getName();
  result += "\n";

  for (vector<Rental>::iterator it = _rentals.begin();
                                it != _rentals.end(); ++it)
  {
      double thisAmount = 0;
      Rental& each = *it;
      amountFor(each, thisAmount);
      // Add frequent renter's points
        ++frequentRenterPoints;

        // Add bonus for new release rental
        if ( each.getMovie().getPriceCode() == Movie::NEW_RELEASE &&
             each.getDaysRented() > 1 )
            ++frequentRenterPoints;

        // Include in result
        result += "\t";
        result += each.getMovie().getTitle();
        result += "\t";

        // Convert int to a string.
        // Output the int object into the output string stream.
        std::ostringstream out_str_stream;
        out_str_stream << thisAmount;
        result += out_str_stream.str();
        result += "\n";
        totalAmount += thisAmount;
    }
    result += "Amount owed is: ";

     // Convert int to a string.
     // Output the int object into the output string stream.
    std::ostringstream out_str_stream;
    out_str_stream << totalAmount;
    result += out_str_stream.str();
    result += "\n";
    result += "You earned: ";
    std::ostringstream out_str_stream2;
    out_str_stream2 << frequentRenterPoints;
    result += out_str_stream2.str();
    result += " frequent renter points\n";

    return result;
}


And I want to move the "amountFor" method into here:

/*  Rental implementation
 */

#include "rental.h"



Here is the customer .h:

If you post because you're getting error messages, it's usually helpful to post the error messages.

You'll need to include Customer.h in rental.cpp if you move the function there.
