I tried to replace the text on the first page index.php with:

} elseif ($category_depth == 'top') {
// This section deals with the "home" page at the top level with no options/products selected
/*Replace this text with the headline you would like for your shop. For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE','Welcome to Outdoor Freedom online store');
} elseif ($category_depth == 'nested') {
// This section deals with displaying a subcategory
/*Replace this line with the headline you would like for your shop. For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE','Welcome to Outdoor Freedom online store'.');
}
?>

Now i have a blank white page..PLEASE HELP!!!!
