I appreciate your not giving up on me. I did manage to get a simple array working with a digital input prompting another value loaded into the array.
I will definitely check out that link and code you offered as the structure approach has piqued my interest as it seems more adaptable should I choose to add other data types like a timestamp.
One area I am yet to tackle is incorporating this array data into part of my boiler webpage display. That may be cumbersome to do but I am up to the challenge.
Thanks for lending your expertise.
