PHP - Mysql & Header Re-direct Urgent Help Please!

Hello,

I'm having some major major issues, with a web hosting / PHP / MySQL database issue and if anyone can help that would be amazing! Okay first I have a MySQL database setup, with a table called "staff", within that there is a "username" and "password" field pretty self explanatory. I have a login in page (login.php) see first set of coding and a loginaction (loginaction.php) and what is suppose to happen is the loginaction checks the posted data against the database and if correct relocate to another page. I have had this coding and much more complex coding working on various other servers, but this is the first time I've ever dealt with BT Business webhosting, which is pretty useless right now and poor help to date from technicians who say it is a purely a coding issue. 

From what I have established I believe that the issue is occuring because BT don't have the apache server setup correctly for what I'm trying to do or that the browser is seeing the "$result" on "loginaction.php" and data, resulting in a white page of  certain doom!

Please help!!
