You need to check if html page can run the php code or not.
If you are using Apache server for running html page, then
the way to execute PHP on a .html page is to modify your .htaccess file. Put following code in .htaccess file:
//for .html:
AddType application/x-httpd-php .html
// for .htm
AddType application/x-httpd-php .htm
For more details, read following link : http://php.about.com/od/advancedphp/p/html_php.htm
Another possible reason can be : File is not available on the given location , so for that check the error_log.
