Checking cells for 2 conditions

[Mary Lancaster]

Hi,
I hope someone can help me with this. I have four cells A1:A4. If all four
cells contain data or are blank then thats okay. But if 1, 2 or 3 cells
contain data then I want a warning that all cells must be blank or contain
data.

Thanks
Mary

Try this:

=IF(AND(COUNTA(A1:A4)>0,COUNTA(A1:A4)<4),"Incorrect entries","")

Change the wording of "Incorrect entries" to whatever message you
would like.

Hope this helps.

One way.

You can use a formula like this in, say, B4:

=IF(OR(COUNTA(A1:A4)=4,COUNTBLANK(A1:A4)=4),"","All 4 cells must be either
filled or left empty")

Maybe give it a bold red font.

More alternatives,

=IF(ABS(COUNTA(A1:A4)-2)<2,"A1:A4 partially filled","")

=IF(AND(COUNTIF(A1:A4,{"=";"<>"})<4),"A1:A4 partially filled","")
