How to make my squarespace form grab a cookie value?

Hi 👋,

I am trying to implement UTM tracking on my squarespace site. First, we want to write a script that stores utm values as cookies for 7 days. Then we want to post those cookies to our squarespace form anytime a cookied user submits. Would anyone know the best way to achieve the second part or suggest a better method?

Hi there, I'm having the same problem. Need to store the UTM parameters on a link, so that we can pass them through a Squarespace form.
