Multiple variable types incorporated with int variable
<p>I have the below code for a simple console application in C#. Whenever I input the AIR rate for the second input I get "input string was not in correct format" as the error. What is the correct format and how do I incorporate it into the current code I have made? I am not familiar with different variable types.</p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int AIR, MIR, PMT, IP, PP, ABorrowed, Term;

            Console.WriteLine("Please enter the amount borrowed on your loan ");
            ABorrowed = int.Parse(Console.ReadLine());
            Console.WriteLine("Please enter the interest rate for your loan ");
            AIR = int.Parse(Console.ReadLine());
            Console.WriteLine("Please enter term of your loan in months ");
            Term = int.Parse(Console.ReadLine());

            MIR = AIR / 1200;

            PMT = ABorrowed * (MIR/1-(1/(1+MIR)^Term));

            IP = ABorrowed * MIR;

            PP = PMT - IP;

            Console.WriteLine("Your total payment for this month is "+PMT);
            Console.WriteLine("Of that payment " + IP + " is interest rate");
            Console.WriteLine("and the Payment Portion is " + PP);
            Console.ReadLine();

        }
    }
}
</code></pre>
