Divide 2 numbers in a databand

[evil]

I have a DataBand that contains 2 rows. How can I divide 1 row by another?
Is it possible to reference a particular cell and divide by another cell?
for example I'd like to divide -16,856,817 and 16,825,000 and get a ratio of -0.99811514

Ideally whats highlighted in yellow, I'd like to add in the FooterBand.

Hello.

You could use the summary tab to calculate the sum.
Or you could use the Before print event to get necessary value to make necessary calculations.
Please, add a variable for this.
Could you specify which our component do you use and we will give you more detailed answer.

Thank you.
