I am attempting to obtain the sum of a column that has duplicate values, and have those duplicate values counted as 1 instance within a specific date range, that is representing the reporting week. So this count should show the count of unique values (kioskID) within that week beginning range.
I have the populate sheet with in E13 I need the count of the kioskID within the date range shown in E9. This count should exclude the duplicate counts.
I have tried countifs, sumifs, frequency and the return value is always 0 when that is not correct. I have tried to pivot the out but I want to avoid using a pivot table reducing manual input to the row in sheet 1.
Example of desired outcome: In week 14 (based on dates in raw data, and the state in source column) count unique values from Raw data Column A, but do not count duplicate values.
