Excel/TTR Formula to Determine if SLA Met


Hello - thanks for taking my question.  I am using the following formula where C5= Start Time & Date and D5=End Time & Date.  Business hours are M-F 8 AM to 4 PM.  The start and end time I am trying to calculate is 7/24/15 5:12 Pm and the End Time is 7/24/15 5:42 PM.  It is calculating at zero time when it should be 30 minutes.  Do you see anything I can correct in this formula?



Sorry to be late in answering--I am answering for Richard who is not well at the present.  I  am not an excel expert, Richard suggests that you try reformatting the time cells.

Hope this works for you, but if it doesn't please reask the question of another all experts person.
