Notice: Undefined index: std in

Hello,

I get the following errors

Notice: Undefined index: std in /home/a/r/ftp_arganolierdk/wp-content/themes/organic_shop/admin/classes/class.options_machine.php on line 63

Notice: Undefined index: std in /home/a/r/ftp_arganolierdk/wp-content/themes/organic_shop/admin/classes/class.options_machine.php on line 170

And here is the code (line 63):

if (isset($value['id'])) $defaults[$value['id']] = $value['std'];
			}

			//Start Heading
			 if ( $value['type'] != "heading" )
			 {
			 	$class = ''; if(isset( $value['class'] )) { $class = $value['class']; }

				//hide items in checkbox group
				$fold='';
				if (array_key_exists("fold",$value)) {
					if ($data[$value['fold']]) {
						$fold="f_".$value['fold']." ";
					} else {
						$fold="f_".$value['fold']." temphide ";
					}
				}

And line 170:

$output .= Options_Machine::optionsframework_uploader_function($value['id'],$value['std'],$value['mod']);
				break;

				// native media library uploader - @uses optionsframework_media_uploader_function()
				case 'media':
					$_id = strip_tags( strtolower($value['id']) );
					$int = '';
					$int = optionsframework_mlu_get_silentpost( $_id );
					if(!isset($value['mod'])) $value['mod'] = '';
					$output .= Options_Machine::optionsframework_media_uploader_function( $value['id'], $value['std'], $int, $value['mod'] ); // New AJAX Uploader using Media Library
				break;

				//colorpicker option
				case 'color':
					$output .= '<div id="' . $value['id'] . '_picker" class="colorSelector"><div style="background-color: '.$data[$value['id']].'"></div></div>';
					$output .= '<input class="of-color" name="'.$value['id'].'" id="'. $value['id'] .'" type="text" value="'. $data[$value['id']] .'" />';
				break;

Hope someone can help.
