Custom Data Validation

Hi

Could someone be kind enough to tell me what is wrong with the following
formula

=COUNTIF($F11:$AN11,$AR11:$BF11,AN11)=1

Thaks

You have specified too many arguments, what are you trying to achieve.

The syntax for COUNTIF is =COUNTIF(range, criteria)
So there are just two arguments while you have 3

Did you mean to use SUMIF?
The syntax is =SUMIF(range, criteria, [sum_range]) where sum_range is
optional
So to sum the second range when the first range has the same value as AN11
you would need
=SUMIF($F11:$AN11, AN11, $AR11:$BF11)
However, the first range F:AN includes 35 cells while the second has only 15
so you will get an error message.

Please tell us more about the problem
best wishes

Just change the first Comma to Colon (.
=COUNTIF($F11:$AN11:$AR11:$BF11,AN11)=1

But in your formula you are including the AR11 in your Countif Range and
again mentioning the same cell as Criteria (AN11)
=COUNTIF($F11:$AN11:$AR11:$BF11,AN11)=1

I think it should be like the below:-
=COUNTIF($F11:$AM11:$AR11:$BF11,AN11)=1

Remember to Click Yes, if this post helps!
