Hi guys, I'm sort of trying to familiarise myself with ASP for the next school year and I am so lost in what I have to do. I've been going through the old notes from last year and I am pretty stuck on a few things. Now I've created two pages on visual web developer and I've got a couple of tasks to put in which are :- On the first page, provide a textbox for the number of products to be checked against a price threshold, and a textbox for the price threshold. (I don't quite understand what this means checking the number of products vs price?? So I don't actually know what I am meant to be doing here.) On the second page, for each product, dynamically create two textboxes: Product name Product price (I think I've sort of done this but not sure if I have done it right? I don't think I've confirmed it, so don't know if it works) 3. Using dynamically-created labels, print out on the second page those products whose price is bellow the threshold, then those whose price is above or equals the threshold. Calculate the total price of all the products, and show it on the second page. (I'm completely lost with this and really haven't got a clue about what to do here) So you can see I have a few problems here. Now here is the code for what I have done :- Page 1 <%-- --%> <%@ Page Language="VB" EnableViewState="True" %> <script runat="server"> Sub Click_Num(sender as Object, e as EventArgs) Session("NumOfBoxes") = txtNum.Text Response.Redirect("default2.aspx") End Sub Protected Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) End Sub </script> <html> <head> <title>This will be a tutorial on OOP - Part 2</title> </head> <body> <form id="Form1" method="post" runat="server"> Enter the number of records to be created <br><br> <asp:TextBox id="txtNum" Width = 150 runat="server" BorderColor="Black" /> <asp:RequiredFieldValidator id="valRF_Num" runat="server" ControlToValidate="txtNum" ErrorMessage="Please, enter a number!"

Because I'm pretty lost at the moment. Thanks to anyone who can help me out here
