I'm having trouble finding an answer in the documentation so I'll ask here:
I have an element representing a weather tower with attributes for temperature sensors at 200 feet and 30 feet. I have a third attribute that I want to represent the stability between those two temperatures.
The stability is determined like this:
A = 200_Foot_Temperature
B = 30_Foot_Temperature
C = A - B
if C <= -1.7 then "A"
else if C > -1.7 and C <= -1.5 then "B"
else if C > -1.5 and C <= -1.35 then "C"
But, when evaluating the formulas, the formula configuration doesn't like the return value. So, is there a way to return strings from an equation?
