It's much more productive to show us your code and the error message. Then
we can see where your misunderstandings lie, and we can try to explain what
you've misunderstood. For example, you might have the right expression, but
be executing it in the wrong context.

In the meantime, use

sum(Table1[productType='Amex']/countType)

with leaderBoard as the context node.
