Hi! Just as a heads up it doesn't look like the intended effect is working.
I had a look in your code a bit, I can see there's some code in the buttons as well as in the contraptions you're using for the ground. I'm not quite sure what the intent is but it looks like you've got some of the syntax wrong, e.g. if you're using a function like "sleep" what you're passing to it needs to be in square brackets like sleep[90].
I don't think that'll be enough to fix it though, since the way sleep works is it blocks all other scripts from running. You may need to try another approach to get this working.
Maybe it would help if you could explain what you're trying to make here?
