I am trying to compare the light value of two sensors, namely s1, & s2 . I don't want to go through the long route which is to save the light values from different sensors to different container, then, compare them. How about using "formula (...)

Are events stackable? Or it works more like "signal()", e.g. in C? e.g. I have 2 different light sensor events set to watch for value higher than 42, yellow & blue.
