Implementation Help

I’ve read through this a couple time and I think I understand it but it is not working.

I have a container with the class of ‘repeater_our_fleet_repeater’ – my repeater field is call ‘our_fleet_repeater’

Inside the container with the class ‘repeater_our_fleet_repeater’ I have a Heading widget and the text of that Heading is #vehicle_title? – and in my ACF repeater field I have ‘vehicle_title’

Also inside that same container I have a Text Editor widget with the text #vehicle_description – My ACF repeater field has the value ‘vehicle_description’

What am I not understanding about the implementation of this plugin. I saw that the plugin was updated 3 months ago so I don’t think its a compatibility issue but rather I am not understanding how to implement the class container and the parameter correctly.

Thanks in Advance
