How do I make CM Courses more than 9 Laps?

I've seen SO Many CM Courses with Laps more than 9 but I can't figure out how it works. How do I do this Glitch?

I have no idea, but if you want to do really long races: Make a really long circuit and put 9 laps.

like this one I made:

You go to the number of laps and go 'inspect element' (f12) and just change the number

This might be unrelated, but I once played a track where the number of laps was a negative decimal. (No, I don't remember the name or creator).

I've seen a track with ZERO laps before. You finish the track by going over the finish line at the start.

I think no one will be able to overcome that challenge.

I don't know why but I've been trying to Click inspect but the word "Inspect" comes up gray and won't let me click it.

you can use much checkpoints for example, if you want 16 laps, you can use checkpoints to give the lap after 4 laps and put 4 laps on the track
