[users] setting primary key in Base

[David Bowman]

I copied some tables from MS Access and tried to set the primary key and 
when saving get the following msg.
SQL Status: 23000
Error code: -10

Attempt to insert null into a non-nullable column: column: LastName 
table: Student Information in statement [ALTER TABLE "Student 
Information" ALTER COLUMN "LastName" VARCHAR(25) NOT NULL]
I would like to know why this is happening and how can I set whatever 
field as primary key
