Creating Relationships Via SQL Server Mgmt Studio Designer

I have created two tables and receive a "columns in table ... do not match an existing primary key or UNIQUE constraint." error message.



Table1: GOSMapping

PK: AuthInd (bigint)

PK: GLCode (nchar(8))

-both columns were set as PK simultaneously



Table2: GOSTracking

PK: AdjID

FK: AuthInd (bigint)

FK: GLCode (nchar(8))



I open Table2 in the designer and right click, then select Relationships. I choose both of the columns that are the PK in Table1, and set the exact fields as the FK in Table2. I get the message when trying to save this relationship. All data types are congruent, and the primary key has been set as the combination of the two PK columns in Table1. Any ideas?
