if (runTime.outlet <= nowTime - lastTime.outlet)
If you are trying to refer to elements in the arrays then you need something like
if (runTime[outlet] <= nowTime - lastTime[outlet])
Time to read up on arrays, methinks.
Then I remembered I can do this "trick" where I can have "arrays", or from the errors above: CLASSES.
So I started to re-write the code with CLASSES, or as I would like to call them: arrays (for now, anyway).
Feel free to call them arrays, because that is what they are. The reference to classes in the errors is because you have used the wrong syntax (see above).
