Template syntax error : Book instance "Renew"

[nameisnot]

I have been going through the tutorials on https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Tutorial_local_library_website.

Up until the Part 9 ("Working with forms") the app had been working as explained in the tutorials. But after created the functionality of "Renew" in the "All Borrowed Books" book lists, I have been getting the subject error.

Error text:

TemplateSyntaxError at /catalog/book/38c0acbc-04eb-4297-b531-66dd3177c29e/renew/

I have gone thru' the related codes all over again (including tried "copy-pasting" codes from both the tutorial as well as the Github pages here) but every time I get the same error.

Grateful for a lead on this.
Thanks

Sorry to be the party-pooper 😊

After posting the issue, realized the mistake (which was, really, as clear as the winter sky!!).

I had forgotten to add the "closing" quote in the declaration of the base template.

Closing the issue.
