Flickr Gallery help

Hi,
i have a little problem with this plugin. The problem is this one:

Parse error: parse error, unexpected ‘?’, expecting ‘]’ in /web/htdocs/www.officialsm.net/home/gallery.php on line 2

I follow the instructions below:

But there is a problem with the Gallery.php faile that i have to put in the root. If i copy and paste the code in the ontructions page it doesn’t work.
I have to change the code in some way?

Anyone could suggest in which way???

Thanks
