 * I am trying to track a count of the categories of posts viewed. I installed GTM4WP
   and enabled Post Count within the plugin in the WP admin. The GTM tag is installed
   through the plugin and is functioning properly. I am trying to setup the DataLayer
   variable in Tag Manager, but I do not see postCountOnPage or postCountTotal as
   an option. Is there a step that I am missing?

 * I’m getting the same error from GTM:
 * The workspace has the following errors:
 * Unknown variable name
    GA4 – Event – Ecommerce events Unknown variable “Event”
   found in a tag. Edit the tag and remove the reference to the unknown variable.
