aspx_beginners thread: Problem with c#?

Hi
I am having a problem with the code in the book: ASP.NET using c#.
In the onstart function I check on if the form element is blank and if it
is the message should not be written.
My problem is that the first time I go to the page the first line comes
out like this: You have selected
But it should not be there at all as far as I understand.
Is this not a good way to check if there is nothing in a form element?
My code is like this:
<script runat="server" language="c#">
void Page_Load()
{
if (Request.Form["list1"] != "")
{
Message.Text = "You have selected " + Request.Form["list1"];
}
}
</script>
<html>
<head>
<title>Drop Down List Example</title>
</head>
<body>
<asp:label id="Message" runat="server"/>
.
.
.

The problem isn't C# its the book your using. The
Page_Load is wrong. You must always ahve these 2
arguments in the function
private void Page_Load
(object sender, System.EventArgs e)
