Help with component expression

[Frank]

Hello, I have the following in Home.Page:

 <component id="InstertAuthorTable" type="contrib:Table">
        <binding name="tableModel" expression="AuthorTable"/> 
    </component>     

Web server reports:

Unable to resolve expression 'AuthorTable' for [EMAIL PROTECTED]

I do not understand what is wrong. What does AuthorTable mean?

Thanks

Frank.
