“Pledge- Odometer” Plug in – any exist?

Hello all,

I’ve been scouring for a plug-in that represents an odometer – to track number of people pledging on a web page.

I’ve checkout out ProgPress, but it had a fatal error when I uploaded it.

Basically, I just need the “Odometer” to read how many people check a box, then reflect the total number.

The functionality and look I’m hoping to find look like the odometer on the front page or 1world2wheels, found here: http://www.1world2wheels.org/

Thanks for any and all help. A point in the right direction is much appreciated.

Adrian
