hi all,
hope you can help...
I have three columns. a, b and c.
a contains peoples names, b contains dates and c contains numerical values (e.g. number of widgets made)
in a separate column i want to specify a date range and person i.e.
d1 = 1.1.07
d2 = 31.3.07
d3 = david white
i would like a function to count all the widgets made by david white during the given time period. i think this might be quite simple but i'm struggling at the moment.
many thanks
