Passing a javascript variable

Hi all,

I’m trying to integrate our signup flow with Ambassador, and to do it we need to be able to pass the new subscriber’s email address and a referral parameter from the URL to Ambassador via a javascript variable.

We’re just using Webflow’s standard forms, and I have no idea if this is possible. Can anyone help me solve this?

Here’s the page I’m trying to do it on: http://inside.com

Thanks so much!
