How can I revise this formula to flag colum A with the following: If B3 is
nontext (date) or "Blank" than "Blank" leave "blank" if not blank than enter
a "3" and If B4 is "blank, than leave blank if not blank than enter a "1"
and if B5 = Blank than leave blank if not blank than enter a 2. If blank row
than leave blank. I want to copy this down the whole column. Thank you.

=IF(ISNONTEXT(B3)*1,3,IF(B4="",1,IF(B5="",2)))
