Flash Stop Watch 00

Hi everyone

I am sure that this is very simple but I simply don’t know the answer.

I am making a stop watch in flash MX. It works very well and everything but it outputs the numbers on screen as a single integer ie 1, 2, 3

I would like it to display numbers 01, 02, 03 so the lap times are in 00:03:45 format

Any help would be most appreciative
