Your reasoning is correct. Whilst the cells A11 and B4 look empty, are you
sure that they do not contain spaces(s). Do a =LEN(A11) and =LEN(B4)
somewhere, if they are not both 0, that is the problem.

Your formula also has a problem if B4 is not 0, but a11 is, as it returns a
#DIV/0! error (dividing by 0 - A11).

Hi Yes i tested the following exactly:
=IF(AND($A$11=0,B4=0),"",(D4-$A$11)/$A$11)

But now the formula part [(D4-$A$11)/$A$11] works even if only one of the
two conditions [($A$11=0,B4=0)] is true. I think the folrmula shouldn't
work
until the both conditions after AND are true.

Hi,
Not sure if the problem lies in the format of the numbers (i.e. text)?
Have
you tested it?
Cheers,

Dear All,

I'm trying to use theIF function as following =IF(And
(y=0,z=0),x,z), but the -AND- logical test isn't working. The formula
part of
the true value is implemented even if the y=0 or z=0 not both of them.

Is there any help.
