why a reference to an empty cell is not considered empty
I do not understand why a cell that contains a formula which result is empty
is not considered as an empty cell. Example: The cell A1 is empty; in cell A2 I type =A1; in cell A3 I type =if(isblank(A2);"empty";"full") and the result in A3 is... "full". I do not get it. Other example:The cell A1 is empty; in cell A2 I type =A1; in cell A3 I type =if(A20;"number higher than 0";"other") and the result in A3 is... "number higher than 0"!!!!.... Even in the case that the value in A2 was 0 how could it be strictly superior to 0!!! That makes no sense at all. Please tell me how to create a reference to an empty cell whose result is indeed an empty cell. I am going crazy.

The presence of a formula in a cell makes that cell nonblank. Even if the
value returned is nothing, it is stlil a returned value. I'm not clear as to what exactly you're trying to do, but how about using doublequotes "" to find a blank value in a cell with a formula? =IF(A2="","Empty","Full") HTH, Elkar "Nicoscot" wrote: I do not understand why a cell that contains a formula which result is empty is not considered as an empty cell.

Stop pulling your hair out!
Example: The cell A1 is empty If A1 contains a formula that returns a formula blank: "", that cell IS NOT EMPTY. If A1 truly was EMPTY then: =A1 would return 0. =if(isblank(A2);"empty";"full") The ISBLANK function does not recognize formula blanks as blank cells so that's why you get "full". =IF(A2="","empty","full") will return "empty". =if(A20;"number higher than 0";"other") If A2 contains the formula =A1 and A1 contains a formula blank, then A2 = "" which is a TEXT value. A TEXT value will ALWAYS evaluate to 0 so that's why you get "number higher than 0". Biff "Nicoscot" wrote in message ...

why a reference to an empty cell is not considered empty
Another way of seeing it is that when I really have an empty cell in A1 and
in A2 I have a formula that says =A1*10 (for example) the result is 0 ... fair enough... ....but if I have in A1 a formula that says =if(ISBLANK(B1);"";B1) (because I realized that if I only say =B1 and B1 is blank than the formula returns 0 instead of blank) and that B1 is indeed a real blank than I do not see any 0 in A1, as I wanted, but the result in A2 becomes #VALUE!. When I want to see the calculation steps I see =""*10 with the explanation the next evaluation will result in an error. I do not understand why Excel cannot considere the result in A1 just as it considers a real empty cell !? "Elkar" wrote: The presence of a formula in a cell makes that cell nonblank.

Thanks Biff
But it is hard to understand the rational behind "TEXT is considered as 0"; I know those are the rules but it does not make much sense... "Biff" wrote: Stop pulling your hair out!

why a reference to an empty cell is not considered empty
So the real question would be do you know any way of having a cell refer to
another cell and actually be considered as a really empty cell if the refered cell is actually empty? i.e. A1 is actually empty and my cell A2 which is refering to A1 is considered just like A1.

But it is hard to understand the rational behind "TEXT is considered as
0"; I know those are the rules but it does not make much sense... The software programmers did that! More specifically, TEXT evaluates to any number. Biff "Nicoscot" wrote in message ...

The short answer is no.
