  1. May 6, 2006 #1
    Hi, i'm working on a students marks evaluation webpage, unfortunatly i run into several problems and i need some help fixing it :smile:

    Code (Text):
    <%@ Page Language="C#" %>
    <script runat="server">

        void submit(object sender, System.EventArgs e)
        {
        lblMessage1.Text = TextBox1.Text;
        lblMessage2.Text = TextBox2.Text;
        lblMessage3.Text = DropListItem.SelectedItem.Text;
        }
        void Calculate(Object sender, System.EventArgs e)
        {
        int TotalGrade = Convert.ToInt32(TextBox3.Text) +
        Convert.ToInt32(TextBox4.Text) + Convert.ToInt32(TextBox5.Text);
        lblMessage4.Text = TotalGrade.ToString();
        }
        int Result
        {
        get { return Convert.ToInt32(lblMessage4.Text); }
         if (TotalGrade <= 100 || TotalGrade >= 90)
             lblMessage5.Text = "A, Excellent!";
         }
         else
         {
           if (TotalGrade <= 89 || TotalGrade >= 80)
             lblMessage5.Text = "B, Very Good!";
         }
         else
         {

            if (TotalGrade <= 79 || TotalGrade >= 70)
             lblMessage5.Text = "C, Good!";

         else
         {
            if (TotalGrade <= 69 || TotalGrade >= 60)
             lblMessage5.Text = "D, Not Bad!";

         else
         {
            if (TotalGrade <= 59 || TotalGrade >= 50)
             lblMessage5.Text = "E, Work Harder!";

         else
         {
            if (TotalGrade <= 49)
             lblMessage5.Text = "F, You Failed!";

    Since this looks like homework I would suggest you look up the difference between the boolean operators || and &&.

    You might also think about how you can eliminate the need for the boolean operator altogether.

    Last but not least you might want to check the syntax on "else if"
