This code makes it multiply by .65 every time. Can someone explain to me why it's doing this?

        private void button1_Click(object sender, EventArgs e)
        {
            double NumberOfPieces;
            double EarnedPay = 0;

            NumberOfPieces = Double.Parse(PiecesTextBox.Text);

            if (NumberOfPieces > 0 && NumberOfPieces <= 199 )
            {
                EarnedPay = NumberOfPieces * .50;
            }
            if (NumberOfPieces >= 200 && NumberOfPieces <= 399)
            {
                EarnedPay = NumberOfPieces * .55;
            }
            if (NumberOfPieces >= 400 && NumberOfPieces <= 599)
            {
                EarnedPay = NumberOfPieces * .60;
            }
            if (NumberOfPieces <= 600)
            {
                EarnedPay = NumberOfPieces * .65;
            }

            EarnedTextBox.Text = EarnedPay.ToString("C");

(NumberOfPieces <= 600)
everything is less than 600 before it, maybe you meant to put >= ?

That was it! Thank you very much! .

This is how I took care of the crash and burn of my program if they entered a letter where a numeric value would go but I don't know how to set one up for the NameTextBox.

What would the code be for making them type only letters into a text box and give them an error if they put numbers?

            try
            {
                NumberOfPieces = int.Parse(PiecesTextBox.Text);
            }
            catch (FormatException) { MessageBox.Show("Please enter a Numeric Value"); }

A better way might be to use int.TryParse(). Try this:

            string text;
            int num;

            do
            {
                Console.Write("Enter some text (no numbers): ");
                text = Console.ReadLine();
            } while (text.Any(c => Char.IsDigit(c)));

            do
            {
                Console.Write("Enter a number: ");
            } while (!int.TryParse(Console.ReadLine(), out num));

            Console.WriteLine("The text you entered was: {0}", text);
            Console.WriteLine("The number you entered was: {0}", num);

If you don't like lambdas or LINQ (you'd have to be crazy not to!) you can always make a ContainsDigit() method that looks like:

        private static bool ContainsDigit(string str)
        {
            foreach (char c in str)
                if (Char.IsDigit(c))
                    return true;
            return false;
        }

And then you just change the do/while loop to: while(ContainsDigit(text));
