How can I pass URL parameters into hidden form field?

In additional to auto filling form elements via url parameters, you can also personalize any part of your page with those same url parameters… I’ve been using Script to level up my no-code mastery, it’s enabled me to create some pretty cool stuff, you should definitely go check it out!

Take care my friend,
