Problem med ´2 tables

hvorfor kan dette ikke køres i "SQL Server Query Analyzer":

CREATE TABLE lokation (
    lokationid int NOT NULL,
    navn varchar(10) NOT NULL,
   
    PRIMARY KEY (lokationid, navn)
   
);



CREATE TABLE afdeling (

    afdelingid int NOT NULL,
    navn varchar(40) NOT NULL,
    lokationid int NOT NULL,   

    FOREIGN KEY (lokationid) REFERENCES lokation(lokationid),
    PRIMARY KEY (afdelingid)

);

Fejlmeddelelsen lyder:
Server: Msg 1776, Level 16, State 1, Line 11
There are no primary or candidate keys in the referenced table 'lokation' that match the referencing column list in the foreign key 'FK__afdeling__lokati__35BCFE0A'.
Server: Msg 1750, Level 16, State 1, Line 11
