Hello

I created an EPUB3 ebook enriched with AR images and animations titled "Mingled Memories":
https://www.edgedpub.com/sample_work_1.php

I was very surprised to see that there were 243 errors. (attached)
However, it's always the same error code HTM_061.

I am not sure what to do. I am afraid that if I change the code in the XHTML file, I will have to change the JS file too.

Is anybody familiar with this issue?

Many thanks.

Daniele
