Sort Order issue

Hi JediMole I have created a Power Query logic that automatically assigns a new Sort Order value to manually entered answers. This prevents errors when sorting by other columns and ensures consistent ranking. Attached the file and power query for your reference.

let
    Source = Csv.Document(File.Contents("C:\Users\jaike\Downloads\rank.csv"), [Delimiter=",", Columns=3, Encoding=1252]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Sort Order", Int64.Type}}),
    MaxRank = try List.Max(List.RemoveNulls(#"Changed Type"[Sort Order])) otherwise 0,
    NullAnswerKeys = Table.Distinct(Table.SelectColumns(Table.SelectRows(#"Changed Type", each [Sort Order] = null), {"Answer"})),
    RankedNullKeys = Table.AddIndexColumn(NullAnswerKeys, "NewRank", MaxRank + 1, 1),
    Joined = Table.NestedJoin(#"Changed Type", "Answer", RankedNullKeys, "Answer", "New", JoinKind.LeftOuter),
    Expanded = Table.ExpandTableColumn(Joined, "New", {"NewRank"}, {"NewRank"}),
    Final = Table.AddColumn(Expanded, "New Sort Order", each if [Sort Order] = null then [NewRank] else [Sort Order], Int64.Type),
    Output = Table.RemoveColumns(Final, {"NewRank","Sort Order"}),
    #"Sorted Rows" = Table.Sort(Output,{{"New Sort Order", Order.Ascending}})
in
    #"Sorted Rows"

Thanks,
