        int m1,m2,m3,m4,m5,t;
        m1 = int.Parse(TextBox5.Text);
        m2 = int.Parse(TextBox6.Text);
        m3 = int.Parse(TextBox7.Text);
        m4 = int.Parse(TextBox8.Text);
        m5 = int.Parse(TextBox9.Text);
        t = m1 + m2 + m3 + m4 + m5;

        if (m1 > 50 && m2 > 50 && m3 > 50 && m4 > 50 && m5 > 50)
        {

            TextBox10.Text = t.ToString();

            if (t > 190)
            {
                Response.Write("First division");
            }
            else if (t > 130 && t < 190)
            {
                Response.Write("second division");
            }
            else if (t > 100 && t < 130)
            {
                Response.Write("third division");
            }

{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string date;
