Created a form in which the user selects a item from a dropdownlist then clicks a button which in turn uses a streamwriter to open a sequential file and displays the data associated with their selection, this is a text file. When I run the solution I get this error control 'btnSubmit' of type 'Button' must be placed inside a form tag with runat=server. I have no idea how to fix this I need help. Below is all my code:

%@ Page Language="vb" AutoEventWireup="false" Codebehind="wfmStockQuotes.aspx.vb" Inherits="Ch13Ex3.WebForm1"%>

YUP!

The server error message is telling you exactly what the problem is:

This line of code, infact all the of the the lines of code below </form> tag need to be between <form></form> tags:

<asp:Button id="btnSubmit" style="Z-INDEX: 104; LEFT: 288px; POSITION: absolute; TOP: 248px"
				runat="server" Text="Submit"></asp:Button>

And with the code you provided, they are not!
