Web Forms :: AppSetting From Master Page Or ASPX?

In my web.config, I have:

<applicationSettings>
<ClientDocs.My.MySettings>
<setting name="AppName" serializeAs="String">
<value>Client Docs</value>
</setting>
</ClientDocs.My.MySettings>
</applicationSettings>

I want to be able to query AppName from an ASPX page. I have tried numerous methods and searched this site:

Here is an example of my code that returns nothing instead of the value in web.config

<% Dim AppName As String = ConfigurationManager.AppSettings("AppName")
Response.Write("test" & AppName)%>
