Scrolling problem

1

i’m working on a mario excitebike game similar to the original excitebike game for nes. i have encountered some problems with the scrolling. i have a movie clip that scrolls as the player goes, and when the mc moves half-way off the screen it resets and counts as a lap. i am trying to find a way to make the laps longer but i cant fit them on the flash stage. i dont know xml yet, is there a way i can do it with gotoandstops?
