<%@ Page
Inherits="System.Web.UI.MobileControls.MobilePage"%>
<%@ Register TagPrefix="Mobile"
Namespace="System.Web.UI.MobileControls"
Assembly="System.Web.Mobile" %>

<script runat="server">
Dim age
Sub AgeClick(sender As Object, e As EventArgs)
age=text1.Text
ActiveForm=Form2
End Sub
Sub Form2_Activate(sender As Object,e As EventArgs)
  message.Text="You are " & age & " years old"
End Sub
</script>

<Mobile:Form id="form1" runat="server">
  <Mobile:Label runat="server">Age?</Mobile:Label>
