Creating photo gallery

Hi everyone, This is my first post here and I really hope someone can help.
I have been using the excellent tutuorial on this site “Create a Photo Gallery” using the script supplied and when i try and test the movie, I fail at the first hurdle and get the error message “Error opening URL: file:///User/ etc etc” is this because I’ve typed something wrong or is there another reason? I’m convinced I’ve checked and double checked it…

Please can anyone help?

Many thanks in advance.
