Map not working when adding a listing

Hi

I (think) this is a multilocation add on issue, hope I’m in the right place to ask..

I’m having trouble setting up my first custom post type. The part where a user enters an address is not working correctly I don’t think. Please see screenshot. The parts where users are asked to enter the country, region and city, do they need to be there? Can I not just let them enter the first line of the address and postcode somehow?

No matter what I try, I can’t get the map to set a location when trying to add a listing. The map doesn’t adjust to the correct location and I keep getting the following error;

Geocode was not successful for the following reason: ERROR

Am I doing something wrong or have I not set something up right?

Thanks

Sally
