Javascript Error

You use Universal Analytics?
Check the checkbox in the Gravity Forms GA settings.
If you use get the error, you dont have a GA script in your HTML.
You need that as well for this plugin to do his work.

We are using Universal Analytics and have this setting checked in the GF settings:

Use Universal implementation instead of ga.js implementation (_gaq)?

This is the GA code in the head of the HTML:

<!-- Google Analytics Tracking by Google Analyticator 6.4.7.3: https://www.videousermanuals.com/google-analyticator/ -->
<script type="text/javascript">
                var analyticsFileTypes = ['pdf'];
                            var analyticsSnippet = 'disabled';
                var analyticsEventTracking = 'enabled';
            </script>
<script type="text/javascript">
	(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
	(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
	m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
	})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

	ga('create', 'UA-51498656-1', 'auto');

	ga('send', 'pageview');

</script>

Then there is the Google Analytics Addon script shown above in the initial post which appears just before the </body> tag.

So why are we getting the error?

I updated the plugin to 0.7.2.
Hopefully it will fix your issue.

That fixed it. Thanks!!

Super! have fun with it!
