Re^2: Array refs problem ...

Yeah I think the problem is with the way I'm dong that somehow. Adding :

printf STDOUT ("1-->%s<--\n", $Row->{ Cells } );
printf STDOUT ("2-->%s<--\n", $FieldOrder );
printf STDOUT ("3-->%s<--\n", $Row->{ Cells }[ ( @$FieldOrder ) ] ) ;

Gave me

1-->ARRAY(0x2af07dc)<--
2-->ARRAY(0x2ab07dc)<--
3-->HASH(0x2b50058)<--
[download]

I don't know what I would have expected for the last one (I think that's like saying $Array[1..4], which surely should be written @Array[1..4], but what do I know ...)
Update Thanks, but tried that first, didn't work, same error.
Update2 Oh wait, I missed that you removed the ( ) around @$FieldOrder also, I seem to be making progress now. Many thanks!

Just like you wouldn't use `$z=($x)+($y)` instead of `$z=$x+$y`, there's no reason to use `@a[(@$b)]` instead of `@a[@$b]`.	[reply] [d/l] [select]
