random number based on what?
let's say for now that you want random number every frame
floor(rand($F)*opninputs("."))

I'm new to houdini and expressions in general, but found this formula to work for one of my switches…

round(rand($F* 0.1)*3)

… if you have more than 4 switch connection, say you have 15, then you could change the formula to this…

round(rand($F* 0.1)*14)

This expression allows for random whole numbers from 0 to 14. A total of 15.

Cheers?
