Another what will appear to be a long thread of updates from this newbie trying to figure out why the customer's referral is not appearing in the Admin/Customers or the Admin/Reports/Customers Referral Report.

I went into the database table for customers_info and looked at the field name
customers_info_source_id and saw that for the five test customers I setup each had a value of "0".

I then edited four of the five test customers to have a value other than 0, such as "1". I then went back to the admin/customers and saw that the four customers now had a referral appearing (finally) under the TABLE_HEADING_REFERRED_BY and the one customer I did not edit had "none" which appears to be what "0" will do.

When I ran the Admin/Reports/Customer's Referral the report showed nothing.
However when I explored Admin/Extra's/Referral Sources what appeared was a count of each of the referral names. So at least now I know that the database will report something on the admin side but for some reason the referral is not being posted in the database when the customer account is created.
