That's not an error, it's a notice. It basically means there's something in your code that isn't perfect.
"Undefined Index" means that in one of your mysql results, there is a lack of the 'id' row.

You can stop this from being reported in php.ini or using PHP: error_reporting - Manual

mysql_fetch_row returns an array with numerical keys (so $row3['id'] will never be defined). You might want to use mysql_fetch_array instead. This returns an array with numerical and MySQL column names by default.
