Here is the playground link

Code block:

Thanks in advance!

But it seems you missed the following.

=OFFSET(Data!$A$1,0,0,COUNTA(Data!$A:$A),2)

You have 5 columns in data but you filled 13 as the last param.

You haven't changed the pivot table data source the the reference MyData

You haven't selected "Refresh data when opening the file".

I've tried to update your pivot but somehow was still getting the error.
However when deleting the pivot and creating it from scratch seems worked.

Thanks @admin !
