Hi there,

Apologies for the earlier answer - it was incomplete, so I started again!

So, you've added the parameter lapsDriven to the existing drive method - we need to change that name as lapsDriven is already used. Let's use laps. That states how many laps the kart will drive. Inside that method you need to deduct laps from barCount, use -= and add laps to lapsDriven; use +=.

In the next task, which implements a drive method that doesn't take a parameter but just drives one lap, call the old method from inside it and pass in 1 so that it just drives a single lap.

I hope that helps,

Steve.
