how can i fix this error?

[torres1]

hi all,

i am writing a weight conversion program that allows the user to input their weight, however i keep getting the same error saying operator '\' cannot be applied to operands of type decimal and double. can anyone help me with this?

here is my code

using System;
using System.Collections.Generic;
using System.Text;
 
namespace WeightConverter

            {
 
                try
                {
                    //Ask's the user to select a type to be converted
                    Console.WriteLine("Select type:" +
                        "\n1) Metric to Imperial\n2) Imperial to Metric\n3) Exit the program.\n");
                    selection = Convert.ToInt32(Console.ReadLine());
 
                    /*if statement which checks if the user wanted to end the
                      program of if they entered a selection between 1 and 5*/

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

You left a lot of code. On what line do you get that error message?
