I am attempting to dynamically update the range for a Named Range in Excel that is used by a Pivot Table.  I have seen some examples but mine is giving me an error {Reference Is not valid.}.

My data source table Starts in cell A4 and Ends in column H.  I named the range "PayDatesDataAll" and following is the Refers To: statement

PayDatesDataAll
="'Pay Dates Data'!$A$4:INDEX('Pay Dates Data'!$4:$1048576,COUNTA('Pay Dates Data'!$A:$A),COUNTA('Pay Dates Data'!$1:1))"

However, when I go to my Pivot Table (which currently just has a static range "a4:H6" and try to replace it with the named range PayDatesDataAll I get an error.  

Columns A, C, and H are formatted as Dates if it makes any difference

If you just type this formula in a cell

=INDEX('Pay Dates Data'!$4:$1048576,COUNTA('Pay Dates Data'!$A:$A),COUNTA('Pay Dates Data'!$1:1)

What is the value/error that you are getting?

Hello,

since you start your index in A4, I assume you want to include all columns that have data in row 4, not row 1.

try

='Pay Dates Data'!$A$4:INDEX('Pay Dates Data'!$4:$1048576,COUNTA('Pay Dates Data'!$A:$A),COUNTA('Pay Dates Data'!$4:$4))

If I do just CountA(a4:a15) I get 6 which is the number of lines that have data

And hence the error. Check teylyns's formula.

Just got it to work with Teylyn's formula with one other variation.  When I went back to my Name Manager to paste her's in mine also had quotations (") at the beginning and end of the reference.  Once I removed those it works.

Thanks to both of you!

I split the points 300 Teylyn/200 Sid since both of you were very helpful but Teylyn's was the exact working reference.

When you copy and paste a formula from EE into the Refers to box of the Name Manager, it will always have " marks that you need to delete. It's not a flaw in the formula but due to the copy and paste from HTML.

Ah I see the error.

To understand it better Here is how Index Formula works...

It gets you the value in the intersection of the row and the column. However your

COUNTA('Pay Dates Data'!$A:$A)  = 12
and COUNTA('Pay Dates Data'!$1:1)=0

That is why it is not able to find a value.

If you use a basic index formula

=INDEX('Pay Dates Data'!$4:$1048576,11,8)

Then it will give you "41090"

The syntax of Index() is

INDEX(array,row_num,column_num)

The formula was fine, basically. But it was counting in Row 1 for the last parameter instead of row 4, where the data to be counted actually sits.
