C++ if statement error on string

I know I'm sounding an awful lot like a newb by asking this however I'm curious as to know why I'm getting an error when using simple operators through an if statement on a string? Here is what I am doing to produce the error:

    void Shift (string updown )
{
    if (updown == "hel")
    {
        //random code
    }
}

and my includes would be:

#include <iostream>
#include <fstream>
#include <Windows.h>
using namespace std;

You are attempting to use the std::string class without actually including the necessary header.

Add #include <string> to your list of includes.

You forgot

#include <string>

Other header files might include the internal header that provides the std::string class, but without the associated functions such as the == operator you're missing.

Well, you know, try to include the <string> header. And either write std::string or add a using std::string after the include.
