Interesting, I came closer by using
grep { %{$DetailSheet{ColumnName}{$_}{XlsColumn}} == 2 } keys %{$Detai
+lSheet{ColumnName}}

[download]

but i got 'can't use string ("-1") as a HASH reference' error, to which, i do use XlsColumn => -1 on the key/values that i don't use in the full 'DetailSheet' hash...

I tried re-inventing the wheel again, but everytime I push it, it still falls flat on it's side...
