Technical Q&A

I didn’t get any good answers the first time i asked so I am going to try again. Here is the situation. I know ABSOLUTELY NOTHING about coding so you need to really simple it down for me. I am trying to add a native ad from amazon to the bottom of only ONE of my pages. I do not want the native ad to show up on all my pages just a single page. I am using the dawn theme.

Here is the link to the page i am trying to add it to: https://vermillo.com/pages/ledger-nano-s

Here is the code for the native ad from amazon:

Please tell me what to do step by step in very simple terms on how i can get this on the bottom of the page I have referenced.

I had this working on the Minimal theme, but it seems to be broken on the Dawn theme now. I have tried a fresh page in addition to my other 150+ pages and it’s not working at all. I don’t know what the issue is but am subscribed to see if others see this problem too!
