get max between multiple columns

[jcastr02]

I am trying to get max from multiple columns in Power Query.  I get an error , stating

"Expression.Error: We cannot convert the value 0.15 to type List.Details:
Value=0.15
Type=[Type]"

Any ideas how to remedy?

hello, @jcastr02 you are missing curley braces {} inside List.Max. There must be a list inside this function like this:

each List.Max({[Column1], [Column2],...,[ColumnN]})
