Hi Everyone - I am iterating through data to build this below hash. Now using the keys and "cat_parent_id" I need to create a string from this looks like "Category1,Category2,Category3,Category4". I am at a loss and hoping someone can help. Thank you. 

$VAR1 = {
          '986172' => {
                        'cat_parent_id' => '',
                        'cat_name' => 'Category1'
                      },
          '986178' => {
                        'cat_parent_id' => '986177',
                        'cat_name' => 'Category4'
                      },
          '986177' => {
                        'cat_parent_id' => '986176',
                        'cat_name' => 'Category3'
                      },
          '986176' => {
                        'cat_name' => 'Category2',
                        'cat_parent_id' => '986172'
                      }
        };
