How do I setup automatic numbering for report entries?

Hi all!

I'm trying to figure out how to have a textbox generate numbers (1-X) for each of the entries on my Report.

My workflow prompts people to enter their address info & then it performs an intersect using their address through 4 different layers, which produces a Report pdf that displays True or False for the intersect results.

     Example Report PDF:      

               Numbers                Employee Name      Layer 1           Layer 2             Layer 3             Layer 4

                    1.                        John Doe                True              False                True             False

                    2.                        Jane Doe                False                True             True            True

                                     Totals:                 1                1                  2                 1

What I need is for it to automatically number down the left hand side of the page each entry. 

ALSO, I'm trying to figure out how to setup another textbox (located at the bottom of each of the 4 columns in my report) to total the number of TRUE values in that column and display that value at the bottom of the report.

I hope I made this as clear as possible, any help would be great! I'm guessing I will need to write some background script in my Report to do this, but I have no idea where to start.

Thank You!
