What’s the error?


Two issues: what’s the error message about and why does it say this will never run when I see lots of lightning bolts.


Not exactly sure, but I would highly recommend reducing your redundancy in that piston. Currently, whenever it starts raining, you have five triggers in this piston all happening simultaneously!?! (each trigger running thru the code top to bottom)


hi Gene,

Two things:

  1. Line 74 has a semi colon at the end of it?
  2. And the crux of your problem is line 84
    It is not recognizing your ‘precipitation’ variable correctly. I don’t know why, however instead of using the variable there just enter in the info that you were storing in the variable as a value for that line statement.

Or do it is an expression and put curly brackets around your variable name in that statement.
