No reason; the formula was imported from a previous year's spreadsheet, and
that's how it came in. I believe it was when we upgraded from XL 2003 to
2007.

the DATEDIF has been modified somewhat, because sometimes there is no date
value in A; just an entry of "Pending", so the formula knows to leave column
H blank.

Thanks.

But if the DATEDIF always gives a number and never an error value, you may
get away with
=IF(H2="","", IF(H2<18,"Yes","No"))


Is there a reason to use
=IF(A2<"",DATEDIF(G$2:G$65536,A$2:A$65536,"y"),"" )
rather than
=IF(A2<"",DATEDIF(G2,A$2,"y"),"")"
Just curious!
best wishes

good morning;

I need to write a statement along the lines of :

=IF(AND(ISNUMBER(H2),H2<18),"Yes","No").

H2 contains the formula
"=IF(A2<"",DATEDIF(G$2:G$65536,A$2:A$65536,"y")," ")"

Obviously, Columns A and G contain dates, which are populated on an
ongoing
basis, not a static set of dates. H2 will not have a number until A2 and
G2
are populated.

The If, And, Isnumber formula returns Yes or No, but when I copy it down
the
column to say, row 44 while the H column is blank, it returns "No"; what I
would like it to do is remain blank until H2 contains a number value.

XL 2007, Win Xp Pro.

Thank you very much for your assistance.
