InvalidValueError: initAutocomplete is not a function Google Places and Autocomplete API

Question

Hope you can help as I've hit a wall, I'm also quite new to using Google's Places APIs.

I'm not going to post any code just yet as my code works fine when the 2 pieces I am about to describe run in isolation.

I am using Google's Places in addition to the Autocomplete API working from the Javascript examples provided by Google.

Initially I had the following script at the bottom of my document:

<script src="https://maps.googleapis.com/maps/api/js?&libraries=places&callback=initAutocomplete" async defer></script>

and this script at the top of my document:

 <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>

This gave me the, "You have included the Google Maps API multiple times on this page. This may cause unexpected errors." so after looking into this I merged both together like this:

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places&callback=initAutocomplete&sensor=false"></script>

However, now that I have done this, I receive the following errors:

InvalidValueError: initAutocomplete is not a function
TypeError: searchBox is undefined

I don't receive these errors when theses scripts are not merged, but I realised afterwards that the functions requiring the Places API stopped working. If I remove the Autocomplete API reference, the Places functions work.

Any ideas on how I can make both of these work together, merging these as shown and solving the 'not a function' issue?

Any suggestions would be much appreciate, please let me know if you really need to see the code.

Thanks in advance, Steph

You should use include script just once, like:

//maps.googleapis.com/maps/api/js?key=__API-KEY__&libraries=places

Note that you omit the 'callback' param when including script. Then load initAutocomplete on window load like:

google.maps.event.addDomListener(window, 'load', initAutocomplete);

Maybe you would need to include gmaps script in head or you would get 'google is not defined' error, if you placed your js inline.
