Clicking game - Operator '-' cannot be applied to operands of type 'string' and 'int' error
<p>Iam making a clicking game, but there is an error i can't get working correctly.
The error is: 
Operator '-' cannot be applied to operands of type 'string' and 'int'<br>
in the private void timer1.tick.
i have been looking on google and this site, but didnt manage to find a compareable error. i've tried the longer minus and the short minus sign.</p>

<p>(made in visual c# 2010 express)</p>

<pre><code>public partial class Form1 : Form
{
    int timeLeft;
    int counter = 10;



    public Form1()
    {
        InitializeComponent();
    }


    private void timer1_Tick(object sender, EventArgs e)
    {
          timer1.Interval = 1000;
          timeLabel.Text = timeLabel.Text - 1;




        {
            if (timeLeft &gt; 0)
            {
                timeLeft--;
                timeLabel.Text = timeLeft + " seconds";
            }
            else
            {
                timer1.Stop();
                timeLabel.Text = "Score";

                MessageBox.Show(Score.Text, "Score");

                Plus.Enabled = false;
            }
        }
    }

    private void Plus_Click(object sender, EventArgs e)
    {
        timer1.Start();
        Score.Text = Score.Text + 1;
        Score.Text = counter.ToString();
    }



}
