I'm trying to write code for a program(windows phone 7) that will convert miles, meters, kilometers.
Everytime I try to run it it crashes. I'm new at this.

Here is my code.... I have 3 text boxes and what I'm trying to do is if I put a number in any one box that the other two boxes will so the conversion.

C#

{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            decimal kilotoal;
            decimal milettl;
            decimal metttl;

          kilotoal = Convert.ToDecimal(KilometersBlock.Text);
          milettl = Convert.ToDecimal(txtmile.Text);
          metttl = Convert.ToDecimal(MetreBlock.Text);

               kilotoal = milettl*1.609m;
               metttl = milettl * 1609.3m;
               kilotoal = metttl / 1000m;
               milettl = metttl * 0.00062137119m;
             milettl = kilotoal * 0.6214m;
             metttl = kilotoal * 1000m;

            answer.Text= milettl.ToString();
            answer.Text = metttl.ToString();
            answer.Text = kilotoal.ToString();
        }

        private void button2_Click(object sender, RoutedEventArgs e)
        {
            txtmile.Text = "";
            KilometersBlock.Text = "";
            MetreBlock.Text = "";

        }
    }
}
