title: Error:The name 'you' does not exist in the current context
body: <p>I have problem with my coding. There is an error which is :</p>
  
  <blockquote>
    <p>Error:The name 'you' does not exist in the current context..
    the ID already exist in the Default.aspx </p>
  </blockquote>
  
  <pre><code>&lt;asp:DropDownList ID="you" runat="server"&gt;
             &lt;asp:ListItem&gt;zed&lt;/asp:ListItem&gt;
             &lt;asp:ListItem&gt;joey&lt;/asp:ListItem&gt;
             &lt;asp:ListItem&gt;john&lt;/asp:ListItem&gt;
  </code></pre>
  
  <p></p>
  
  <p>and Default.aspx.cs</p>
  
  <pre><code>string stat = you.SelectedValue.ToString();
  </code></pre>
  
  <p>But when I debug the program, it say that the 'you' doesn't exist in the content. Why does this error occur and how can I fix it?</p>
