Are you using strict and warnings? I suspect that you may not be as you should be getting an error similar to below

Global symbol "%site" requires explicit package name at foo.pl line 10
+1.
Execution of foo.pl aborted due to compilation errors.
[download]

Your array contains references to hashes so you need to dereference them to get at the contents.

$site->{'Age'}
[download]

Alternatively so you can use $site{'Age'}; you can do this.

my %site = %{$recordset_TA_SITE[0]};
