title: Perform analysis on last three values of a FileMaker dataset
body: <p>My end goal is to have a box change color when the last 3 records input into a field (based on the time of input) in FileMaker achieve a certain criteria (ex. variance &lt; 2). I would like to know how to make this happen, or how a calculation/script can be written to only look at the last 3 records.</p>
