Hi,
I am computing for weekly counts of leads generated for my report and I am using countifs formula and refer to the working sheet where my data is located.
I am pretty sure that I am referencing in the correct Date Column and it's data type is also a Date. But the formula is prompting an "Invalid data type error". When I try to use the formula to the working sheet itself and select a range of cells, it is working. Please see the screenshot below.
The first image shows my formula referencing to the working sheet, but when I hit enter it prompts "INVALID DATA TYPE". The second image is the my reference column. The third image is when I tried the formula to the working sheet itself and it is working.
Please help on how can I fixed the "INVALID DATA TYPE" error.
