谁能帮我看看这是什么问题？
小弟初学，现写了一个程序如下：<%@ Page Language="VB" %>
<script language="VB" runat="server">
Sub tbMessage_Change(Sender As Object, E As EventArgs)
lblMessage.text = "Hello" + tbMessage.Text
End Sub
</script>
<html>
<title>List0104</title>
<body>
<font size="5">Sam's Teach YourSelf in 21 Days: Day 1</font><hr><p>
<%Response.Write("Our First Page<p>")%>
<form runat="server">
Please enter your name:
<asp:textbox id="tbMessage"
OnTextChanged="tbMessage_Change"
ranat=server/>
<asp:button id="btSubmit" Text="Submit"
ranat=server/>
<asp:label id="lblMessage" font-size="20pt"
ranat=server/>
</form>
</body>
</html>
总是提示：“Name 'lblMessage' is not declared”，我觉得这个变量已经声明了呀！
请各位大大指点一下！
