So, I have a book that half the toc is not there. Somehow it disappeared during the conversion. I want to re-do the table of contents, but I am stuck on one element: navPoint ID

So the structure of the toc in the editor looks like this:

<navPoint id="e6b9b7f1-4d07-4035-b7cc-ecf312b63a1b" playOrder="50">
<navLabel>
<text>44: FRIENDS</text>
</navLabel>
<content src="9780440338871_95230_split_055.html"/>
</navPoint>

So I get the playOrder part, but where is this coming from: "e6b9b7f1-4d07-4035-b7cc-ecf312b63a1b"?

Thanks for any help!
