OK, so my new issue is the following error:
Error while parsing file: element "a" not allowed here; expected element "address", "blockquote", "del", "div", "dl", "h1", "h2", "h3", "h4", "h5", "h6", "hr", "ins", "noscript", "ns:svg", "ol", "p", "pre", "script", "table" or "ul" (with xmlns:ns="http://www.w3.org/2000/svg")
This is in reference to a line that was a location for a link elsewhere in the book. In the HTML code, I used:
<a name="TCOOS"> <p class="subtitle">THE COLOUR OUT OF SPACE</P>
In calibre, it changed that to:
<a id="TCOOS"> <p class="subtitle" id="calibre_toc_16">THE COLOUR OUT OF SPACE</p>
<p class="subsubtitle" id="calibre_toc_17">
I assume I can't just take out "a" but I am not sure what to replace it with.
Thank you!
