"To debug this code, open x5g49.js in Developer Tools"-message keeps showing. How do I connect a sku to my code?

I am very new to coding, so bear with me. I’m trying to code in an option to add gift wrap to the cart page. I created a product called gift wrap and assigned it sku: 001. I added the code, but it keeps saying the product name cannot be recognized. Any ideas how to adjust my code to make it work? Photos attached:
