I'm afraid we do not have anything to go off of to help you.

If I wanted to write a report that compared Ducks to Cars how would I do it?

The only thing I could do is have 2 Rows 1 row Says Ducks, and one row says Cars, and 1 column that has the total.

But there would be no way for me to relate them, join them, or break them down.

So what problem are you trying to solve?
