Configuration Error on initializeData="<app root directory>\Asptesttrace.log" />

I am following the Walkthrough: Integrating ASP.NET Tracing with System.Diagnostics Tracing document and when I get the section on Routing All Tracing Output to .NET Framework Tracing it said to add the following the to the trace section in the web.config

<add name="TestTracer" 
        type="System.Diagnostics.TextWriterTraceListener, System, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 
        initializeData="<app root directory>\Asptesttrace.log" />

The initializeData="<app root directory>\Asptesttrace.log" /> part is giving a compile error. In visual studio the it said the app root and directory part need tags. When run the default.aspx page there error shown in the webpae is

Server Error in '/' Application.

Of I am stumped what is wrong?

Can you see that you have break the xml format ? You can not add this

<app root directory>

inside the the tag, you break the xml format.

Remove the and if you have permission to write, its going to work

<add name="TestTracer" 
        type="System.Diagnostics.TextWriterTraceListener, System, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 
        initializeData="Asptesttrace.log" />

<app root directory> : this is the part that you need to change by hand, and type your application root path, if that was visual studio says, but its not a parameter that find its. Eg: c:\inetpub\vhost\yoursite.com\httpfiles\Asptesttrace.log
