Hey all,

Currently following this Shopify tutorial to get any external links on my website to open in a new tab and it's unfortunately not working. The theme I'm using is MOTION. 

The website for reference is https://kathy-santo-dog-training.myshopify.com/ (pw: ksdt)

Thank you in advance for any help anyone can give me to get this working!
