Thanks so much jbrugger. I don't mean to trouble you much. But how can I make these parts:

%{$HoHoA{'set'.$i}}
[download]

and this:

%{$HoHoA{'set'.$y}}
[download]

Be made more flexible. Because this secondary key (key1_set1 ..etc) can be "totally random". I wrote it that way for easiness in explaining. Really hope to hear from you again.
