You need a public class for Form1 to initialize.

See this code:

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

        private int counter = 60;
        private void button1_Click(object sender, EventArgs e)
        {
            //Insert your code from before
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            //Again insert your code
        }
    }
}

I've tried this and it all worked fine

If you need anymore help feel free to comment :)

Use Timer for this     private System Windows Forms Timer timer1      private int counter   60     private void btnStart Click 1 object sender  EventArgs e               timer1   new System Windows Forms Timer            timer1 Tick    new EventHandler timer1 Tick           timer1 Interval   1000     1 second         timer1 Start            lblCountDown Text   counter ToString               private void timer1 Tick object sender  EventArgs e                counter--          if  counter    0              timer1 Stop            lblCountDown Text   counter ToString
