I want to pull header of a part of my landing page by tag manager, when someone click on read more button . so I use this tutorial: https://measureschool.com/relative-click-variable/ but it couldn't work
then, I use this tutorial: https://www.simoahava.com/analytics/css-selector-guide-google-tag-manager/
but it couldn't work
how can I fetch this header or something like that by custom javaScript in tag manager?
