Checking for Duplicates within a Workbook
Hi, I am using the following array formula to check for duplicates within a
worksheet.
{=IF(MAX(COUNTIF('Daniel S'!A4:A1000,A4:A1000))1,"Duplicate","No
Duplicates")}
Is there a way that I can extend this so that it checks the same range
across 10 worksheets within a workbook.
Thanks
