Problem begins at string SunshineWeb::getCustomerName(), where it underlines getCustomerName() and states the following:
Error:declaration is incompatible with "std::string SunshineWeb::getCustomerName"
(declared at line 12 of "c:\users\user\documents\visual studio 2010\projects\project 2\project 2\SunshineWeb.h")
And this is the main file / executor thingy:
// creates SunshineWeb object, inputs products and displays
// total quantity and retail price of products inputted.
#include "SunshineWeb.h" // includes definition of class SunshineWeb
int main()
{
// creates SunshineWeb object
SunshineWeb mySunshineWeb("Sunshine Web Store");
mySunshineWeb.displayMessage();
mySunshineWeb.inputProducts();
mySunshineWeb.displayProductTotal();
} // end main
My second problem is with SunshineWeb mySunshineWeb("Sunshine Web Store");, where it underlines Sunshine Web Store and states:
Error: no suitable constructor exists to convert from "const char[19]" to "SunshineWeb"
Just beginning to learn C++ object orientation programming, and this is a program I wrote for class - what gives? I googled and went through my notes, but it doesn't help / solve this problem at all. What really bugs me most is the no suitable constructor part, as I can simply throw all Customer Name related functions out of the window, as I haven't even implemented it yet, seeing as I can't get it working ; but maybe there's something I'm missing. Either way... I need help! Please save my baby!
Edit : Thanks for the help, I've noticed my error and tried tweaking it like suggested, so my header file now looks like :
// Definition of class SunshineWeb that counts Product 1, Product 2
// and Product 3 retail prices. Refer to Project 2.cpp for member
// functions.
#include <string> // program uses C++ standard string class
// SunshineWeb class definition
class SunshineWeb
{
public:
SunshineWeb( std::string ); // constructor initialises customer name
void setCustomerName( std::string ); // function to get customer name
std::string getCustomerName(); // function to retrieve customer name
void displayMessage(); // displays a welcome message
void inputProducts(); // inputs a number of products
void displayProductTotal(); // total number of what products
private:
std::string CustomerName; // customer's name
int Product1Count;
int Product2Count;
int Product3Count;
}; // end of class SunshineWeb
This fixed the incompatible declaration error (a simple typo mistake) from earlier, and I'm not sure if it fixed the error with no suitable constructor, because while the nasty red underline is gone, I still can't run the program : I opened up the error list from Visual Studio 2010, I see a couple of errors:

Yes, I am a complete amateur making (mostly) silly mistakes, but for the love of my life I can't seem to find a solution to my seemingly-simple problems. These problems makes no sense whatsoever, and I'm quadruple checking everything. Thanks for the help (and patience displayed), I really appreciate it.
