Eloqua sum up non-number lines?

Hi,

I am pretty sure this is easy but I cannot figure out how to add the sum cell that will calculate the number of rows at the bottom?

I am talking about the rows that do not contain the number but text only. For example: I have a a column with names and I want Insight report to sum up the number of rows at the bottom.

name 1 | City 1

name 2 | City 2

name 3 | ........

Total: 3 2
