Lab1 Excercise 3: Duplicate Column

I have created the query for exercise 3 and applied all the changes that are listing. As I try loading the data, I get the following error.


Column 'Country Name' in table 'Country Population' contains a deplicate value 'Canada' and this is not allowed for columns on the one side of many-to-one relationship or for columns that are used as the  primary key of the table.
