This is one in a small series of Google Maps related projects – you may be interested in Google Places API and Google Maps as an Input Control. Alternatively, if your project does not intend to use Google Maps, consider the Leaflet / MapBox example which does not require a Google Maps API Key.
Please remember that the Google Maps license key in the PDF file and in the Project will not work for you. It is bound to certain IP addresses and domains. You will need to get your own.
Please remember that projects like this one are debugged more easily in the browser. To run a debug in the browser, click Ctrl+F5 in place of the usual Debug Button.
