I am kind of starting to understand what you’re saying Joy. So I need to tell my javascript function which one to process? I guess I assumed it would just use the active one but that also explains my lack of knowledge for php.
I used metaboxe.io to create a custom post type and the rwmb_meta is how to get the field value of that metabox. They are numbers, but I set the metabox up as a text, would that cause an issue?
I’m sorry, I guess I should have said when the name of the custom post is clicked, the custom field’s value will set the marker’s new coordinates.
