Well, my searches have brought up only one post on the subject of how to write a formula to add up hours and minutes in excel to create a logbook. See
here This however is addressing a little more advanced problem than I have.
So, can anyone point me (someone who has never written an Excel formula before!) to a idiots guide on how to format sub-total and total cells for adding up hours and minutes? So that I can have running sub-totals (like each page of a logbook) and a grand total?
I thank you in advance.
