I have a list of items in column A and for some of the items, column B has value "Y". How do I only include the items of column A marked with "Y" in a data validation list?
I have tried this in the data validation formula but doesn't seem to work:
INDEX('Mysheet'!$A$8:$A$240,SUMPRODUCT(--('Mysheet'!$B$8:$B$240="Y")))
