Google Map not displaying on frontend

Compliments of the day,

I noticed the Google Map is not displaying on the front end of my site. At the back end, when you insert the address, the map displays quite fine. However, when you come to the front end, all that shows is a white box. (see attached).

Kindly advise.

Hi,

Thanks. I have inserted the key and the map is now showing.
However I noticed a little issue. Is there a way to decrease the map box size so that the map area within the box is bigger? Presently, a user will have to scroll down within the box to see the map. (See attached).

Kind regards

Hassan
