Interestingly, you can actually use tables to bypass most of the if/then stuff here, like this. local dirs = ["go 9e, 9n, 18w, 2s, 16e, 5s, 2w, 3n, 2w, 3s, 2w, 3n, 2w, 3s, 2w, 3n, 2w, 3s, 2w, 3n, 2w, 3s, d", "go 11s, 18e, 8n, 2w, 6s, 2w, 6n, 2w, 6s, 2w, 6n, 2w, 6s, 2w, 6n, 2w, 6s, 2w...

It works fine for me if floor is the number 1. If however floor is the string "1" send doesn't fire, but ends up being 2.

You probably need to add a line at the start.
