Count Cell Values based on Time Range

Question

I want to get the total "Contact" made between the times on column G and H using the Start(Col D2) and End(Col E12). How to accomplish this?

Answer 1

Use a sumifs to do this

=SUMIFS($B:$B,$D:$D,">="&G1,$E:$E,"<="&H1)

Edit: Use the following

First sumifs checks to see if a contact has started in the specified range, the second sumifs checks to see if a contact has ended in the specified range

=SUMIFS($B:$B,$D:$D,">="&G1,$D:$D,"<="&H1)+SUMIFS($B:$B,$E:$E,">="&G1,$E:$E,"<="&H1)
