Unable to Display Information with Code

I need to embed code into my site using Wix Editor, but it is not displaying the data. The provider of the code has checked and everything looks OK on their end.

The code has been inserted on this page (https://www.nachodaddy.mx/vallarta-calendar). I see it in there, but nothing is being displayed. They referred me to another page where others doing this without an issue. (Add Us to Your Site - Vallarta Calendar)

I’m not sure what I am doing wrong. Can you offer any suggestions on how I can make this happen? Is this a limitation of WIX?

Thank you for your time.

Are you able to expand on what the code is/should be doing, and which part of the site it should be displaying on? (What it’s meant to look like)

Here is a screenshot of what it looks like on another site along with a link.

This is one of over a dozen other websites that display the calendar, so it is not an issue there.

If I understand correctly, it’s displaying correctly on the page itself like this:

However, you have code added to the Custom code area in your site dashboard (Dashboard> Settings> Custom code) that is displaying it above the header

I will remove the code from the header. Thanks for your help.
