WampServer

Hi All, I just installed WAMP v 3.2.3.3 64 bits on my Windows 10 PRO laptop for the first time. I do not have IIS turned on as a Windows feature. I'm trying to execute php code within an .html file. However, I can't get php to echo anything out. File name extensions are shown, so I know it's an HTML (.html) file. I modified my Apache .httpd.conf file like this (added the last line)
