Here's my code for SQLServer_Include.aspx:

<%@ Page Language="VB" Debug="true" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SQLClient" %>

<script runat="server">

'================================================================

    Private Function ConnectionString () as String

        Dim servername, username, password, databasename As String

        servername = ""

        username = ""

        password = ""

        databasename = ""

        Dim conString As String

        conString = conString.Format("server={0};User ID={1};Password={2};Database={3};", servername, username, password, databasename)

        Return conString

    End Function

 </script>

  I am getting the following error message:

Parser Error Message: Server includes are not allowed in server script tags.

Source Error:
