I've set up a custom post type to display family tombstones on a genealogy site with custom fields. I am wanting to display two openstreetmaps giving address and map location of two cemeteries.
I added a text custom field named "MapBox One Address", id "mapbox_one_address" giving the address of the cemetery
I then added an openstreetmap custom field named "MapBox One", id "osm_ij6ndsblkl" with field "Address field*" filled with "mapbox_one_address"
Added the next two fields identical to the above, only changing the "one" in the identifiers to "two" and id of the openstreetmap as "osm_57k4z23cl5b"
Added the two addresses on the custom post page and everything displays properly
Added a two html blocks each inside it's own div on my page to display the two maps side by side using this code:
