title: Reject User input if Input is Less than Total Amount
body: <p>Good day, I checked all the existing code to find a way through this but since i am a new one, i can't solve it without a guide. </p>
  
  <p>On this code, it only accept integers but i want to prevent the user to accept input if input is less than computed total amount</p>
  
  <p>For example, User input is 5 and total amount is 10, the program will still accept that and that's an error, </p>
  
  <p>So where will i put if Amountended &lt; TotalAmount then loop again</p>
  
  <pre><code>bool test3 = false;
          do
          {
              try
              {
                  Console.SetCursorPosition(67, 19);
                  Console.Write(" ");
  
                  Console.SetCursorPosition(67, 19);
                  AmountTended = decimal.Parse(Console.ReadLine());
                  test3 = false;
              }
              catch
              {
                  test3 = true;
              }
          } while (test3);
