PHP help - Forward to HTML page?

[Desmo]

I've got some PHP script to upload some files (different from the last one I was using), and after it has finished, I'd like to forward on to a different html page.

I've tried using... header("location:http://www.blahblahblah/blah.html");
but that doesn't want to work properly, I think it's the wrong command.

I just need to forward to the html page once the files are uploaded.
