Hello,

I can't figure out how to write a formula to count unique entries in different groups.

My goal is to have a non-excel user to just paste the content of a worksheet ( monthly) and get the stats done automatically. I am not sure if this can be achieved by Pivot Table because I did not see it....... :|

I got this:
{=SUM(IF(Monthly_Transaction!F:F="DISTANCE",IF(FREQUENCY(IF(LEN(Monthly_Transaction!C:C)>0,MATCH(Monthly_Transaction!C:C,Monthly_Transaction!C:C,0),""), IF(LEN(Monthly_Transaction!C:C)>0,MATCH(Monthly_Transaction!C:C,Monthly_Transaction!C:C,0),""))>0,1)))}

and it worked. However, when I change the content of the reference sheet, this will not work.

I will probably have to give up if I can't get this done in the next week. sigh

Configuration: Windows XP
Firefox 3.0.5

This is a special formula in excel. In order to update this formula you have to enter into cell with F2 and then Ctrl+Alt+Enter. This will update the formula however will automatise your work :((
