Nice 1. But since it is DV, even though *array*, you don't need to hit the
CTRL+SHIFT to enter, works just fine without it.

In DV Custom enter the following *array* formula:

=(SUM(LEN($B$7:$F$7))=1)*ISNUMBER(MATCH("X",$B$7:$ F$7,0))

Since it is an array formula press Shift+Ctrl+Enter rather than just
enter or clicking the OK button.

Hi

My data is in range B7:F8. Row 7 and 8 is merged (B7/B8, C7/C8 ... E7/
E8) is merged. Therefore in all I have five cells.

I want an input "X" or "x" in one of those five cells. (Only one
input, more than one is not allowed)

If anyone gives two inputs
OR
if anyone types anything besides "X" or "x"
OR
if anyone types anything of length more than one character

It should give a validation error box with a message.

Can someone give a formula to enter in the validation box?
