for the curious, i'm an idiot :)

in the past i have always created anon hashes setting arrays = arrays. well, this time it should have been scaler = scaler, but i just didn't see it. everything else fell out of doing that all wrong. code i ended up using:

my %hash;
foreach my $string ( $try->param ) {
        if ( $string =~ m/(\d+)_(\d+)/ ) {
                $hash{$1}{$2} = $try->param($string);
        }
}

and  <P> then you have:<BR><P>$hash{12}{1} which prints "then you have STRING".
