Help Importer Help

Hi, i am trying to update from DBTech Gallery. In my old vBulletin database i have a couple of fields under dbtech_gallery_images that i would also like to import across. These are roll_id and award_id

Just wondering how i would edit the DBTechGalleryPro.php file to allow it to import these fields?

I have something like this:

Code:

                $import = array(
                    'album_id' => $albumId,
                    'content_data_id' => $photoData['content_data_id'],
                    'title' => $parser->render($this->_convertToUtf8($attachment['title'], true)),
                    'description' => $parser->render($this->_convertToUtf8($attachment['text'], true)),
                    'user_id' => $userId,
                    'username' => $username,
                    'content_privacy' => array(
                        'allow_view' => 'everyone',
                        'allow_view_data' => array(),
                        'allow_comment' => 'everyone',
                        'allow_comment_data' => array()
                    ),
                    'roll_id' => $attachment['roll_id'],
                    'award_id' => $attachment['award_id'],
                    'view_count' => $attachment['views'],
                    'position' => $position,
                    'content_state' => 'visible',
                    'content_date' => $attachment['dateline'],
                    'content_updated_date' => $attachment['dateline']

But i get error when it goes to import the photos.
Mysqli statement execute error : Field 'roll_id' doesn't have a default value
