I moderate a few forums..so I know how aggravating noobs are.

Anyway..
Trying to form a basic Calorie Counter App.. (Visual Studio 2010)

My issue is that it appears my methods are not being called properly, I simply need to accept user input, and call the method (a simple method that multiplies the user input * a variable) and then display that answer out into a label. For some reason all I am getting in the output label is the exact input the user enters.

Code:

namespace Calorie_Calculator
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        //Methods:
        private double FatCalories(double Fat)
        {
            return Fat * 9.0;
        }

        private double CarbCalories(double Carb)
        {
            return Carb * 4.0;
        }


        private void fatCalloriesButton_Click(object sender, EventArgs e)
        {
            //Variables for Fat Carbs & Calories
            double Fat, Calories;

            //Get Number of FAT Grams
            if (double.TryParse(fatTextBox.Text, out Fat))
            {
                //Calculate Calories from Fat:
                Calories = FatCalories(Fat);

                //Display Fat Calories:
                outputLabel.Text = Fat.ToString("n1");
            }
            else
            {
                //Error Message:
                MessageBox.Show("Enter a valid Number.");
            }
        }

        private void carbCallorieButton_Click(object sender, EventArgs e)
        {
            //Variables:
            double Carb, Calories;

            if (double.TryParse(carbTextBox.Text, out Carb))
            {
                Calories = CarbCalories(Carb);

                outputLabel.Text = Carb.ToString("n1");
            }
            else
            {
                MessageBox.Show("Enter a valid Number.");
            }

            
        }

        private void exitButton_Click(object sender, EventArgs e)
        {
            this.Close();

Any thoughts as to why the heck this isnt working? Again.. just a noob here.
