Decoy Drill (Desert) = Aack! What am I missing!?

[Mother_Nature]

Please help…

TypeError: s is undefined

Why is it throwing an error?

[Mother_Nature]

I changed nothing…
Went back in 2 hours later…
Now a different error !?..

I have used this code multiple times in other levels… why is it throwing an error now?
