    Have Mercy 1st Post Visual C#

    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:
    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.

    Perhaps I need to elaborate a bit more..rather than being so vague.

    The app simply needs to use the methods to calculate the number of callories from fat grams as well as from carb grams.

    What isn't working? No values show up? The values are incorrect? What?

    You are passing the user input to the output label:
    Code:
    outputLabel.Text = Fat.ToString("n1");
    You need to pass the calories value to the output lable:
    Code:
    outputLabel.Text = Calories.ToString("n1");
