in thread Hash Problems

Ok, so I figured out this part, but now my problem is that I need to have the hash set up so that I have a many keys (file names) and each key has multiple values (parsed from the files) these bascially need to be set up like this: 
%pers_dcr_files = (

    'Name' => [
                'RightNavLaunchDate'        => "",
                'RightNavExpirationDate'    => "",
                'LinkURL'                    => "",
                'SmallGraphic'                => "",
                'ShowHome'                    => "",
                'ShowPersonal'                => "",
              ]                
        
);

# Hash for Business Page

%bus_dcr_files = (

    'Name' => [
                'RightNavLaunchDate'        => "",
                'RightNavExpirationDate'    => "",
                'LinkURL'                    => "",
                'SmallGraphic'                => "",
                'ShowHome'                    => "",
                'ShowBusiness'                => "",
              ]                
        
);            

# Hash for Home Page

%home_dcr_files = (

    'Name' => [
                'RightNavLaunchDate'        => "",
                'RightNavExpirationDate'    => "",
                'LinkURL'                    => "",
                'SmallGraphic'                => "",
                'ShowHome'                    => "",
                'ShowBusiness'                => "",
                'ShowPersonal'                => "",
              ]

I had these initial settings in my code, that is what was causing the array/hash error, but how do I set up my hashes in this manner to proceed with my program and not break the logic from the previous part?

    I don't think that you are gaining anything by setting up these initial values for the hashes. You should be able to just comment out those three assignments and have everything work.

      Yeah, I did that and it seems to work fine, one final question on this subject, the data output looks like this: 
      $VAR5 = 'Test2';
$VAR6 = {
          'ShowHome' => 'Home',
          'RightNavExpirationDate' => 20010520,
          'RightNavLaunchDate' => 20010510,
          'ShowPersonal' => 'Personal',
          'SmallGraphic' => '/templatedata/components/msn.gif'
        };

      Just for one instance, is this telling me that 'Test2' is the key and {the whole list from var6} are the values? That is how I am interpreting it...

        Yep, that's right. What's happening is that Dumper doesn't know you're passing it a hash; it just gets a flattened list of values, and prints them one after another.

        I probably should have suggested this instead: 

        use Data::Dumper;

print Dumper \%home_dcr_files;  # ref to hash, for nicer formatting

        You had Dumper called wrong. Because it's often so one can read it nonetheless. Call it "Dumper \%hash" ("\" is important) and you will see what it really means:)
