Thanks for the tutorial - I've completed up to the end of section 3 (Adding more features). When I amend the install.php file at the start of section 4, I get warnings about "Undefined array key "count"" and "Undefined array key "error"" on lines 94 and 95, and when I then try to view index .php I get "Fatal error: Uncaught PDOException: SQLSTATE[HY000]: General error: 1 no such table: post in C:\xampp\htdocs\blog\index.php:7 Stack trace: #0 C:\xampp\htdocs\blog\index.php(7): PDO->query('SELECT\r\n ...') #1 {main} thrown in C:\xampp\htdocs\blog\index.php on line 7"

Any advice much appreciated.
