title: There can only be one 'page' directive - How do I fix this?
body: <p>I am pretty new to c# and asp.net and I've encountered an error on a page with the error stating that </p>
  
  <blockquote>
    <p>"There can be only one 'page' directive."</p>
  </blockquote>
  
  <p>The code is as follows:    </p>
  
  <pre><code>&lt;%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="AddUser.aspx.cs" Inherits="OEPD.AddUser" %&gt;
  </code></pre>
  
  <p>I have this page linked into another page using the 
  <code>&lt;!-- #include file="~/Admin/AddUser.aspx --&gt;</code> function.This page is also using the MasterPage </p>
  
  <pre><code>&lt;%@ Page Title=" Admin Home" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="AdminHome.aspx.cs" Inherits="OEPD.Admin.AdminHome" %&gt;
  </code></pre>
  
  <p>How do I fix this? So it not only links in, but works without errors?</p>
  
  <p>Thanks in advance.</p>
  
  <p>p.s this is my first question so I apologise if it seems a bit vague.</p>
