Simple inventory program - no operator matches these operands

[oN3k92yv]

Hey, I'm trying to make a simple inventory program, but whenever I run it, it starts to say no operator matches these operands. I'll upload a picture of the errors in a minute.

Here are the errors: http://i.imgur.com/00bTcqu.png
Can anyone tell me how to fix it?

/*This program calculates inventory data*/

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
#include <sstream>

using namespace std;

int main()
{
	string tool;
	double unitCost;
	double numberOfUnits;
	double totalCost = 0;
	char ch = ' ';
	bool done = false;
	ifstream input;
	

	int counter;

	ifstream inFile;
	ofstream outFile;

	inFile.open("janeInventory1.txt");

	if (!inFile)
	{
		cout << "Cannot open input file. Program Terminates! " << endl;

		return 1;
	}

	outFile.open("janeInventory1.out");

	for (int i = 0; i<6; i++)

	{
		cin >> tool >> numberOfUnits >> unitCost;
		cout << tool << " " << numberOfUnits << " " << unitCost << endl;
	}

	return 0;


	outFile << fixed << showpoint << setprecision(2);

	inFile >> tool >> numberOfUnits >> unitCost;

	while (inFile)
	{
		totalCost = numberOfUnits * unitCost;

	}

	cout << "**************************************************************************" << endl;
	cout << "Inventory for Jane Doe National Hardware " << endl;
	cout << "**************************************************************************" << endl;
	cout << endl;
	cout << "ITEM         NUMBER OF UNITS              UNIT COST ($)                  TOTAL VALUE " << endl;
	cout << "***************************************************************************" << endl;

	ch = ' ';

	while ((ch = input.peek() != EOF))
		string tool = "";
		double units = 0.0;
		double cost = 0.0;

		input >> tool >> units >> cost;
		
		cout << left << setw(9) << tool;
		cout << left << setfill << (' ') << setw(15) << units;
		cout << left << setfill << (' ') << setw(25) << cost;
		cout << left << setfill << (' ') << setw(20) << numberOfUnits * unitCost;

		totalCost = 0.0;








	}
; }

setfill << (' ')

setw(15)

One of these things is not like the others. Hint: review function call syntax:
