Ok, so I have researched and researched and have been through my code dozens of times, and I can not seem to figure out why I keep getting:

error C2678: binary '>>' : no operator found which takes a left-hand operand of type 'std::istream'

here's a snippet of my code:

Code:
#include "ItemType.h"

void ItemType::addListing(ofstream& output) const
{
	output.open("prgmlisting.dat");

	if(!output.is_open())
		cout << "sorry cannot open file!" << endl;
	else
		{
			cout << "please enter name of channel: ";
			cin >> channel; //This is where I keep getting the error
			output << channel << endl;
		}
}
Also note that I have included #include <string> and #include <iostream> in ItemType.h
