Please help. I can't find the correct approach to take.
On line 27 of this page . . .
https://www.warrencampdesign.com/samuel/part1/week15.php
. . .
I call for a page menu titled "samuel-part1_menu.html," shown here: https://www.warrencampdesign.com/samuel/part1/samuel-part1_menu.html
When I did a W3C test for the menu page, it told me that it needed a doctype, language, head, and title tags.
I added all four and uploaded the menu.html file. I then checked my "week15.php" page for W3C validation and it declared a "stray doctype" on that page because the page already has a doctype at its top and now has one (apparently) in that "samual-part1_menu.html" page that I called for on line 27.
What's needed to verify the actual page and the menu page?
I need to understand the correct approach to take because I have more than two hundred files that have a "_menu.html" page called for, so I need to make it right in every case.
Thanks, in advance.
