I need to set up a spreadsheet with an button to create and send an email automatically which i can do but i also need it to do one thing before 16:00 hrs (today) and another 16:00 to 23:59. e.g. they press the button at 15:00 and a message box would display "Before 16:00 hrs): If they press it at 16:01 the message box would say "After 16:00 hrs). I've not really used time before and have no clue how to start.Thank you
