Hi wil,

You'd have to program a few definitions of when the "morning" session starts and end, and the "afternoon" session too. From there, you'd have to decide whether you want the function to display the information as time elapses during each session (i.e. in real time) using the HighestSince() and LowestSince() functions, or you could do it retrospectively by nesting the Highest/LowestSince in a ValueWhen() function.

There are many ways to achieve these sorts of results in MS. To get the best results from this community forum, have a crack at writing the code yourself, then if you get stuck, post your best attempt here with an explanation of what the cide is supposed to be doing and a description of how the code is not achieveing the results (a picture speaks a thousand words, so add one if you can)

Hope this helps.
