Google Map API location not showing up as it should when I load the browser

<%= @topic_view.topic.title %>
<%= @topic_view.topic.average_rating %> <%= @topic_view.topic.posts.count { |p| !!p.custom_fields['rating'] } %>

I should see a map of my current location being displayed but I do not.

You are getting a 403 error which means the API key is invalid.
