How can you tell an indicator (SMA, ATR, SRI, etc) to use a time period "one higher" than the default time period?

OK, I'll answer my own post. Unless you have a better suggestion, it seems the only way is to have an array of IF statements comparing the defaultPeriod with each Period time that is available (5min, 10min, 15min, etc) and then ASSIGN the correct Period to a new Period variable, as shown here:

BUT THIS DOESN'T WORK!!! I don't know why, but it looks like some kind of variable type mismatch, even though I have "period" as the variable type for all variables.
