I seem to have an array of hashes, I need to look up a each key => values in the hashes. I am not able to loop through each hash and find the key => values more than once. I know this is a very simple beginner problem and I have been reading stuff on Perl for days including: http://www.perlmonks.org/?node=References%20Quick%20Reference http://perldoc.perl.org/Data/Dumper.html and the all Perl books I have. What I am posting here is some code I whipped up that replicates the problem I am getting. I recreated the PR variable with the output of Data::Dumper in the real program, thats why I said 'seem to have an array of hashes' because I am not sure I am reading the output correctly but it matches what I get from this little bit of code. I created some variables that would be present from program. When I run this code I would expect HASH ELEM: to print the contents of each anonymous hash in the array not just the first one. 
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

#test program          
#set up some test data:
my $form;
$form->{"id"} = '12594';
$form->{"cleared"} = '1';
print  qq| ID: $form->{"id"} $form->{"cleared"}\n|;
#set up what we seem to get from the web program
#an array called $form->{PR}
#another unnamed array called $VAR1 by data dumper?
#var1 contains a list of hashes
@{ $form->{PR} } = (
