Creating events in Google Tag Manager seems pretty straightforward but if your events aren’t reporting in Google Analytics, check your configuration.
A web analytics tool like Google Analytics can help you understand the data behind the user experience of your website. A tag management tool, like Google Tag Manager, enables you to customize your web analytics solution and capture more data.
Google Tag Manager allows you to collect data without heavy lifting on the development side. You can deploy all kinds of third-party–not just Google products–tags, or snippets, of code to enhance your data collection and web analytics solution.
Once you’ve installed Google Tag Manager on your site, you can deploy Google Analytics with Google Tag Manager.

Check Google Tag Manager Configuration
If you dig into it, your web browser’s debugging tool will show errors for unknown and undefined parameters that prevent Google Analytics from running commands in the code and thus prevent the code from sending data to your Google Analytics account.
The reason for this is that the person who created the event tag added a Google Analytics Settings variable into the Tracking ID field, either in the tag itself or the settings variable used in the tag.
The Tracking ID field can only accept a string of your Google Analytics tracking ID, “UA-XXXXX-Y” or a variable, either a constant or from a Lookup Table, that returns that string.
The Google Analytics Settings variable returns a configuration object instead of that Google Analytics tracking ID string. That’s what causes the errors.
The most simple solution is to fix the Tracking ID field. That will enable the tag to fire correctly.
