I'm just coming up on this article and wondering if someone can help with my implementation.

I took the code you mentioned in the original article and added it to my footer in Squarespace. I then created a hidden field in the form and called it "GCLID." I then tried a made up gclid in the URL like https://www.webesite.com/?gclid=Cj0KCQjwz7C and submitted the form but I'm not seeing them come through on the form submission. Is there a missing step?
