Hiding elements if the field in the content manager is empty

This question is similar to this post

My knowledge of coding is nil, and I was really hoping that hiding an element if the field is empty was something that happened by default, but alas, it looks like I need to learn a bit of coding.

Screenshot of the situation:

I want to hide the “Apple Podcast” image when there is no link to that effect in the content manager. the present coding doesn’t yield an error message when I test it, but the element keeps showing in all entries of this set, despite only one having a link in the appropriate field.

Appreciate your output and hel
