Long live open source!
I could not do it either, use this site, its awesome
I think you;ll find it makes more than 1 file, in fact it makes one for each game in your pgn.
For example, if you call your file Carlsen.html and it has 6 games, it will make 7 files: Carlsen.html, Carlsen_1.html, Carlsen_2.html........Carlsen_7.html.
The Carlsen.html file will not show a board, only notation. The others all show boards, and you can navigate between them.
I have this working on my pc, how to upload it you will have to ask some one else, I dunno.
You have this Pgn Viewer at this page
