linq ro sql question

Since I am working on a my second  C# asp.net webforms page that I have ever done, I have the following question:

In a linq to sql connection that I setup with a datacontext object I did not include the organization table in the .dbml file since I received error messages that the objects in the table were already declared in the same namesapce. I can not remove the organization table from the other datacontext object since that other datacontext object is already used in production. (I am adding some webpages that will be a url link offf of the main company page. I want to use the general webssite namespace instead of creating my own to keep the coding easier.)

Basically what can I do to include some of the columns of the organzation table to be joined with the tables in the my new .dbml file.
