While creating your directory listing, click on the "Extra Fields" tab.
You will see the screen below.
Fill in your location (state or city)
Adress 1 (street address),
Make sure you fill in the Latitude and Longitude values for your address.
The latitude and longitude fields will determine your exact location on the map.
(To save time, just do a longitude and Latitude search for your city on google or other search engine. Your Longitude will be a negative figure.)
Wrong or interchanged values for longitude or latitude will result in a misplaced map location for your listing.
