So many problems!

From the PHP online Manual

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include, or require, functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

So basically if you want to make the browser load a new page using header() you have to execute the header() before any other data ( HTML ) is sent to the browser. It is also a good idea to follow any header() with an exit; .

This might not be too difficult in your case as it looks to me like this code should go at the top of the script and not here in the middle of it anyway.
