    This is basically the calculation I want to perform.

    Percent Error = ((Instrument - Reference) / Reference) × 100
    or
    ((f_27-f_24)/f_24)*100


    Please check : https://doc.tiki.org/CalculationsQuestion
    For your case it should be something like (to be tested)

    Copy to clipboard
    (mul (div (sub f_27 f_24) f_24) 100)


    My 2 cents, I prefer working with identifiable permaname and not the f_n' form (IE: "peopleAge").
    You may want to add rounding operation and some check in case a field is empty.

    Good luck
