1) Give a description of the problem
Global Variable does not seem to read as a value to the piston
2) What is the expected behaviour?
Piston will read global variable and fire/not fire based on less/greater than.
3) What is happening/not happening?
It is not comparing the value of the global piston.
4) Post a Green Snapshot of the piston
You can see in the second image that the comparison should be true for @rainexpected
What am I doing wrong?
