Cassina is a manufacturer. Its _pkManufacturerID is '27' and there are 30 entries in the Products table that have 'Cassina' selected as a value for the _fkManufacturerID field.
Do those 30 entries have "Cassina" or do they have "27"? They should have "27".
If they are "27", are _pkManufacturerID and _fkManufacturerID both the same type (usually should be type Number)?
Thank you very much!
