Analytics w/form - Tracking refferals not working

I have read and tried all your recommendations and still have a problem.

When people fill out a jotform they are taken to a custom URL thank you page. The form is embeded as an iframe for best viewing on my website.I am trying to track form conversions in google analytics. No matter how I set it up the "referrer" is always  --- submit.jotform.us / referral I need to track the funnel on where the traffic came from that filled out the form and ended up on the "/thank-you" page??traffic source --> landing page with form --> the sources that actually filled out the formall I get is the form as the referrer!
Any help is greatly appreciated!Thanks,Matt

Hi,

Adding the submit URL (submit.jotform.us) to your Referral Exclusion list would do the trick.

Note, that the form submit domain name might be a bit different, so here are some examples:

submit.jotform.com

submit.jotformpro.com

submit.jotform.us

submit.jotform.co

Kindly do that and update us here for the results.

Thank you!
