Count from 1985 - 2005

Hi,

Real rookie one here. Can anyone tell me how to setup flash so i have one movie clip that is a static number, and then another that counts from that number upto another number?

i.e. 1985 - ‘number that rapidly runs from 1885 to 2005’

Also can this be done with text or do i have to have an image for each number?

All help is much appreciated.

Cheers,

Pat
