There are a few ways to use COUNT. For one, you can either count rows or fields. To count rows, I usually use the number 1 as the argument (some people like to use * instead). And when counting fields, you can either just name the field to count all non-null values in that field, or precede it with the word DISTINCT to count only the unique values of that field.

To facilitate a more thorough analysis of your issue and a more specific answer, be sure to show your SQL code and provide a link to the course page you are working with.
