Question How to create Relationship with duplicate records ? (1 Viewer)

[hullstorage]

Hi all,

Please see attached picture where I am stuck at?

I have a table that holds UK Postcodes and a customer table that holds customers.

I am trying to create a relationship between the 2 so when I enter a postcode in the customer table this is then related to the postcode table.

the main problem I have is that there is a lot of duplicate postcodes in postcode table so the primary key is simply a number as you will see in the picture.

Any help please?

Thanks
