your script is totally messed up, it doesn't work at all

First of all, you have to use = instead of := whan you want to CHANGE a variable of an object, such as collideSet. So your code is written like this:

e.geom.collideset := 1

but it should be

e.geom.collideset = 1

for it to work.

Also in the bend menu there is something seriously messed up because there is no code there. Can you tell me what you wrote there so that I can correct it?

You may want to download the scene to see what I mean, the circle that changes gears is just vibrating

on a side note, you should use restitution 0 on your gears
