I have a spreadsheet where I am trying to extract some information from raw data.
In Column F there is a list of telephone numbers and in Column D there is a number which equates to duration in minutes.
I have to break down all of the data into different areas. So I currently have many lookups similar to =SUMPRODUCT(--(LEFT($F:$F,4)="1281")) This will find all of the telephone numbers that begin with 1281 in Column F. For example, on one sheet the total instances of 1281 is 19.
What I need to be able to do is lookup those 19 instances but then also lookup column D and sum the total duration in minutes for all 19 instances of 1281 only.
Any ideas on a formula I would use to do this?
Thanks in advance!
