In hind site, Ideally what I would like is when iI click the macro button that activates the code it prompts me for the ending time because the start time was automatically captured as being the active cell. with this code. Mod it confirms the active cell time is correct but I still have to click ok to get the prompt for the ending time
The above will save me a click

I'm think that at the end you get a message box that shows what the start was, what the ending time was and the break time deducted. And of course what the answer the is as a complete check

Do not know if this is possible

Still testing your suggestion will post test results later
