Hello,
After doing a lot of research about how to use GTM to track form submissions into GA as Goal Completions, I mainly followed this article: https://nettlesnet.com/marketo-form-tracking-google-tag-manager-analytics/
Whenever I preview and test, it works, but after having it live for over a week, the GA goal completions (and even GA events that came in) is drastically lower than the number of actual people who 'filled out form" when I pull it from Marketo as either a Smart List or Landing Page Conversion Report.
After some more research, stumbled on a lot of discussions from @SanfordWhiteman to include an eventCallback to the GTM tag, so I did - but upon preview in GTM, it keeps giving me the error "Parse error. '}' expected (screenshot of error attached).
So I have 2 questions:
1. Is this Custom HTML in the GTM tag correct? I have subsequent Trigger (that fires on All Pages) and Universal Analytics Tag to send this back to GA
2. If the above is correct, what's causing this error when I added in the eventCallback?
Thanks!
