1. How do you prefill hidden fields?

1. How do you prefill hidden fields? 2. Google Analytics has a cool URL builder, and I'm trying to fill some hidden fields on my form with the tags. Is that possible?

I figured out how to prefill hidden fields, thanks to the guide found on the forum here: https://www.jotform.com/help/71-Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters 

I still don't know if it is possible to prefill hidden fields with google analytics tags. I created a separate post to ask the question: https://www.jotform.com/answers/1004772-Passing-Google-Analytics-tags-as-text-into-a-jotform-field#0
