& -> &#038 in Google maps URL

Hi,
I’m trying to integrate google maps into a directory website I’m setting up but the google maps API key requires sensor to be set to either true or false – which you’ll see here:
http://www.closergrocer.co.uk… obviously i’ve set this in my coding to:

https://maps.googleapis.com/maps/api/js?v=3.exp&key=AIzaSyAbImA_-tcNB8CPkkoYD4RQEUQrkGPODQY&sensor=FALSE …

only when i check my site’s source it reads:

https://maps.googleapis.com/maps/api/js?v=3.exp&key=AIzaSyAbImA_-tcNB8CPkkoYD4RQEUQrkGPODQY&sensor=FALSE&ver=3.5.1

(Line 21) (I’m not worried about the end ver=3.5.1 – just the & conversions)

Having done some research I’ve found wordpress automatically converts & to & … Though I’ve tried a few edits of functions and formatting files, the source always comes back the same…

please help!!
