Averaging Value between Two Serial Dates
Hi all,
I have two spreadsheets. The first spreadsheet contains two columns, one for
start date/time (in serial format) and the second for stop date/time (in
serial format).
The second spreadsheet contains two columns. One containing a serial
date/time and the other containing a meteorological value (eg. temperature).
I want Excel to read the start and stop date/time from the first spreadhseet
and then search the second spreadsheet for all temperature values which were
recorded during this time frame.
Lastly, I want Excel to average these values.
Is this possible using a single Excel function?? Or will I have to use many
nested functions?? Would it be easier to use VBA and if so where would I
start?? Any help would be greatly appreciated. Thanks
Chris
