I might not be sure what you mean, about using an array for all of that, but within one line of code, it is taking care of a variable that will change depending on the config island variable. Otherwise I would have needed to use a switch statement, which is a whole lot more than just one variable. But then again if your array solution would work in one line.. then I would love to see it!
