Default Error in Ch. 14 Try It Out

I'm working on the try it out "Inserting and Deleting Data with the ListView Control". I think I've followed all of the instructions, but when I click "Insert" on the "Manage Photo Album" page, I get this error:

Unable to update the EntitySet 'Picture' because it has a DefiningQuery and no <InsertFunction> element exists in the <ModificationFunctionMapping> element to support the current operation.

Any one see this before or have an idea? I can go through the exercise again, but I'm hoping I just missed something.

Thanks
