Okay, I thought I had it all figured out. First book has been validated. Then applied those coding changes to second. I am now experiencing the following error: element a from namespace not allowed in this context.
The code is as follows: <h2><a class="chapter" id="c1_1">MK#1: MAJOR KARNAGE</a></h2><h3>CHAPTER ONE</h3>
When I open it in sigil, it has changed it to:
<p><a class="chapter" id="c1_1">MK#1: MAJOR KARNAGE</a></p>
<h3 class="calibre4" id="calibre_toc_15">CHAPTER ONE</h3>
So it has stripped out the h2 and replaced it with <p>.
Any ideas?
