While loop with a return value function

MatieA (26)
I'm having a problem here, and if someone could point me in the right direction, it would be most helpful.
I've pasted the error message below, and then my code below that:

Description: Lab 4 Fundamentals Ch4 Ex2
New Concepts: 
	A while loop and a return value function
Challenges:
	First value functions; add a second function to determine commRate

#include <iostream>
#include <iomanip>
#include <cmath>
#include <string>
using namespace std;

// Declare constants

// Function Prototypes
double CalcComm( double galSold, double commRate);
double detRate(double galSold);



int main()
{
	// Declare variables below here
	double galSold, comm, commRate;
	
	// Initialization Section for real number output. DO NOT MOVE!
	cout <<setiosflags(ios::fixed | ios::showpoint);
	cout <<setprecision(2);
	// Begin your "main processing" below here
	cout <<"Please enter the number of gallons sold. Enter 0 to end."<<endl;
	cin >>galSold;
	while (galSold != 0)
	{

		comm = CalcComm(galSold, commRate);
		cout << "For a sale of " << galSold << " gallons the commission is $" << comm << endl;
		cout << "Please enter the number of gallons sold. Enter 0 to end. ";
		cin >> galSold;
	}
	return 0;
}
double detRate(double galSold)
{
		if (galSold < 500)
		{
			return .03;
		}
		else
		{
			return .04;
		}
}


// function definitions below here

The function CalcComm is not defined anywhere.

Oops I figured out what was missing here; it's working now.

Thanks for the help.
