Google Map Error

I'm getting an error with my goog开发者_C百科le map script. Obviously I've messed up something to do with setting it to true or false?

Your URL is

http://maps.google.com/maps/api/js?sensor=set_to_true_or_false

As the alert already says, you need either

http://maps.google.com/maps/api/js?sensor=true

or

http://maps.google.com/maps/api/js?sensor=false

I hope you are following the tutorial, and you should have come across this sentence:

Note that we also need to set a sensor parameter to indicate whether this application uses a sensor to determine the user's location. We've left this example as a variable set_to_true_or_false to emphasize that you must set this value to either true or false explicitly.

In the line You have ...&sensor=true_or_false.
Set it to ...&sensor=true or ...&sensor=false. :-)

The error seems pretty clear to me: the URL you're using looks like this:

http://maps.google.com/maps/api/js?sensor=set_to_true_or_false

The error requests simply that you decide whether that "sensor" parameter should be considered true or false.
