First of all, I understand that its better to put the context here. however I didn't to create multiple copies of this question around the web. and thought some1 could get some points on stack overflow in the process.
The questions till persists here, is how do I actually get the value of this mapping into the table. because I tried to do what you mentioned and it just changed the value of the name of the keyword to the value of the searchvol.
I want to be able add a reference a keyword, and have keystone admin UI grab any other attributes I might need that are related to that keyword, such as search volume.
