Hi James,

I deeply appreciate your help!

Below is the JSON export, and here are three screenshots that I hope you’ll find helpful. Unfortunately I cannot change the Theme or plugins, it’s a live site and the current Theme and plugins provide a good deal of the site’s functionality – the whole thing would break if I switch.

That said, I really don’t think this is related to the Theme or other plugins, I believe that it’s simply my own inexperience with PHP (I’m a very novice coder) – I just don’t know how to structure my code so that it will show the header (“Additional Resources”) and then links IF there is data entered in at least 1 row, and not show either if there is not – I think looking at the screenshots will help the most, along with my code snippet above.

Here are the screenshots:

Here’s my JSON export:
