I have a sheet named "XYZ Activity" with meeting dates in column B starting with cell B4. There are duplicates in this list, that should only be viewed as one meeting. On another sheet, each company that attends the meeting has a specific join date found in Column C (C4 is the first company start date). I am trying to figure out an equation that will count how many meetings the company could have attended. I already calculate the total meetings they have attended using either of the following equations:
=COUNT(1/FREQUENCY(IF('XYZ Activity'!$C$4:$C$4000=A3,IF('XYZ Activity'!$B$4:$B$4000<>"",'XYZ Activity'!$B$4:$B$4000)),IF('XYZ Activity'!$C$4:$C$4000=A3,IF('XYZ Activity'!$B$4:$B$4000<>"",'XYZ Activity'!$B$4:$B$4000))))
=SUM(IF(FREQUENCY(IF('XYZ Activity'!C$4:C$5000=A4,IF('XYZ Activity'!G$4:G$5000="Yes",MATCH('XYZ Activity'!B$4:B$5000,'XYZ Activity'!B$4:B$5000,0))),ROW('XYZ Activity'!B$4:B$5000)-ROW('XYZ Activity'!B$4)+1),1))
Any help would be greatly appreciated.
