What does this error mean when setting up a yahoo fantasy football league?

When I try to advance from the "scoring settings" page, it says "You must provide a valid League ID#. (Error #623)". Does anyone know what that's all about and how I can fix it?

Just add the ".00" after the ammount. In my case the form was displaying "0". I added the ammount followed by the ".00" and worked.
