Formula does not apply to the column
I have this table, and I want the average of the column EC(mS/cm) on the column next to it, group by name. I used this formula yesterday but today it does not work when I apply it to the column. If( Row() == Col Min( As Column( "EC (mS/cm)" ) << By( :Name ) ), Col Mean( As Column( "EC (mS/cm)" ) << By( :Name ) ), . ) Thank you in advance!
