currency conversion program functionality...please help!!!

Please post in code Blocks, it makes reading the code a lot easier. I repost your code for redability:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string userResponse = messageModule();            
            while (userResponse == "Yes")
            {


                inputModule();
                conversionModule(inputModule());
                outputModule(inputModule(), conversionModule(inputModule()));
                Console.WriteLine("Do want to convert more money?Y/N");
                userResponse = Console.ReadLine();
            }    
            
            Console.WriteLine("Thanks and goodbye");        
          

        }
        public static string messageModule()
        {
            string userResponse;
            Console.WriteLine("You can convert Pesos, Eng Pounds, Euros, Yen, and Canadian dollars into U.S.\ndollars. Do you want to continue?Yes/No");
            userResponse = Console.ReadLine();
            return userResponse;
                        
        }
        public static string inputModule()
        {
            string currencyType;
            Console.WriteLine("Please enter the currency type that you want to convert?");
            currencyType = Console.ReadLine();
            Console.WriteLine("Is this the type of currency that you want to convert?Yes/No: " + currencyType);
            string confirmation = Console.ReadLine();
            while (confirmation == "No")
            {
                Console.WriteLine("Enter the currency that you want to convert.");
                currencyType = Console.ReadLine();
                Console.WriteLine("Is this the correct currency type?Yes/NO");
                confirmation = Console.ReadLine();
            }
            
            return currencyType;        
        }
        public static double conversionModule(string currencyTypeToBeConverted)
        {
            double euros = 0.7676;
            double EngPound = 1.6433;
            double Pesos = 9.5085;
            double Yen = 104.9200;
            double CanDollars = 1.4690;


            double amountInForeignDollars;
            double amountInUSDollars = 0;
            string userResponse;
            Console.WriteLine("Please enter the amount of " + currencyTypeToBeConverted + " that you want converted into U.S. dollars");
            amountInForeignDollars = Convert.ToDouble(Console.ReadLine());
            Console.WriteLine("Are you sure that you want to convert this amount: " + amountInForeignDollars);
            Console.WriteLine("From " + currencyTypeToBeConverted + " to U.S. dollars?Y/N");
            userResponse = Console.ReadLine();
            while (userResponse != "Y") 
            {
                Console.WriteLine("Please enter the correct amount");
                amountInForeignDollars = Convert.ToDouble(Console.ReadLine());
                Console.WriteLine("Is this the correct amount?Y/N" + amountInForeignDollars);
                userResponse = Console.ReadLine();   
            }
            if(currencyTypeToBeConverted == "Euros")
            {
                amountInUSDollars = amountInForeignDollars * euros;
            }
            else if(currencyTypeToBeConverted == "Eng Pound")
            {
                amountInUSDollars = amountInForeignDollars * EngPound;
            }
            else if(currencyTypeToBeConverted == "Pesos")
            {
                amountInUSDollars = amountInForeignDollars * Pesos;
            }
            else if(currencyTypeToBeConverted =="Yen")
            {
                amountInUSDollars = amountInForeignDollars * Yen;
            }
            else if (currencyTypeToBeConverted == "Canadian dollars")
            {
                amountInUSDollars = amountInForeignDollars * CanDollars;
            }
            
            return amountInUSDollars;
        }
        public static void outputModule(string currencyType, double amountUSDollars)
        {
            Console.WriteLine("The amount of money in " + currencyType);
            Console.WriteLine("Is " + amountUSDollars);        
        }


    }
}

Please specify wich part you "have to repeat" and in wich case. From lapheal's reply I figure it is the Input Module:

conversionModule(inputModule());
outputModule(inputModule(), conversionModule(inputModule()));

The reason is that you call it twice, instead of calling it once and storing the result in a varriable.

Side Notes:

Module is not an ideal name for a function, consider naming it Function instead.

The ideal construct for 'console input loops' is the do...while loop (it solves the "run at least once" problem):
