Re^5: grep confusion

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...

You are probably missing a comma in your "unused' key. This works: `DESCRIPTION => { .... }, UNUSED => {XlsColumn => -1} } );` [download] My print statement works without complaint: `print grep ({ $DetailSheet{ColumnName}{$_}{XlsColumn} == 2 } keys %{ +$DetailSheet{ColumnName}} ) ,"\n"; # Note - grep params are enclosed in parens.` [download] All power corrupts, but we need electricity.

I've tried several variations of the grep suggested and either get strict errors or 'arbitrary' values from other values in the hash, I may have to resort to a for loop with an flat array using the XlsColumn values as the array indexes. thanx for the idea though, I'm always looking for shortcuts and I hoped grep would help.
