What is wrong with this if then statement?

then you won't see the error, you probably have incorrect db login information, you can put these two lines on top of your file:
ini_set("display_errors", 'On');
ini_set("error_reporting", E_ALL);

No its the correct data I've checked it like 50 times.

Did you already look, if there is any output with mysql_error()?

The first 2 conditions are just updating the database, it's not outputting anything, so you will see a blank page and the database is updated
