supplier1 111-1111

However, it doesn't help with the error message because I'm
not trying to alter the Products table, as the error message
suggests, I'm trying to create a new table, SupplierSuppliesProduct,
containing a relationship between two already existing tables. The
new table would look something like:
Table: SupplierSuppliesProduct
with primary keys SupplierName,ProductName
showing which Supplier supplies which Product.
How should I do that?
First define this third table as new table and then set the
relationships. It is a n:m structure.
Kind regards
Regina
Ah! Yes. Tried it and it works.
Seems obvious now.
Thanks.

Larry
