Forgive me if this seems trivial but I have spent a considerable amount of time trying to make this work. In trying to import the very first list, in this case, Vendors,  with only two input lines into a new instance of Odoo using the TEST IMPORT command. Odoo posts a message: "No matching record found for external id 'base.state_us_' in field 'State' at row 3." Using the "Get all possible values" lists a number of cities none of which are in the US are shown. The only way to clear the error is to hard code "base.state_us_**" putting the actual numeric code for the state in the csv file where I have shown **.

What am I doing wrong? I have googled this for hours, searched the community blog, read all the documentation I can find to solve the problem. This should not be this difficult.

Your help would be greatly appreciated.
