Incrimenting variable

#1

1) Give a description of the problem
I’m trying to incriment a variable based on a value returned from a function, its always returning “0”. This is related to another post, but was advised it would be better to start a new thread. Also cleaned up the code for simplicy

2) What is the expected behavior?
Variable gets incrimented

3) What is happening/not happening?
Variable stays at 0

**4) Post a Green Snapshot of the piston![image|45x37]

#2

Force $weather.etc into a decimal, decimal($weather.conditions.current_observation.visibility_mi)

#3

That did it. When I read the weather API documentation it said it “returns a decimal”, so I never considered it wouldn’t get handled properly.

Thank You!
