  <p>here's my code: </p>
  
  <pre><code>public partial class Form1 : Form
  {
      public Form1()

          InitializeComponent();
      }
  
      private void calculate_Click(object sender, EventArgs e)
      {
          double total = 0; //total amount
          double tip = 0; //tip percentage
          double meal = 0; //meal amount
  
          tip = Convert.ToDouble(tip.Text) / 100;
          meal = Convert.ToDouble(meal.Text);
          total = (meal * tip);
          total.Text = "$ " + Convert.ToString(total);
      }
  
      private void Form1_Load(object sender, EventArgs e)
      {
  
      }
  }
