I have a form that I want to track conversions for. This form uses AJAX to reload, so I want to use Element presence trigger to capture the class that appears after a form is submitted (I’ve found the Form submission trigger unreliable in the past). This form is also on a page with other forms that have the same submission message class. So, I wanted to use the form’s data-form-ID _and_ the submission message class in the trigger. This way, I can capture form submissions for only that form. Is it possible to do this? Is there another way to do this? I’ve tried combining the class and ID (e.g. .SubmissionMessageClass[data-form-id=“12345-12345-12345”]), but the tag won’t fire. The tag _will_ fire when the Element presence CSS selector is just the class (e.g. .SubmissionMessageClass). ---

Hi! You could add two separate element presence triggers and combine them in a [trigger group](https://help.piwik.pro/support/tag-manager/trigger-group/): ![image](https://europe1.discourse-cdn.com/flex005/uploads/piwikpro/original/2X/a/ad1d0b2b11b36bac36be84e1c0ea574479f5378b.png)
