PDF FORM - GPS INPUT

Question

I am making a pdf form using acrobat XI on a mac (OS 10.6) and want to have a button to press that will input GPS co-ords into form fields, derived from the device (tablet, android, idevice)
Someone else asked the same question in a forum, got the following javascript, and a number of people commented that it worked fine on all devices, and yet i get SyntaxError 4: line 5.
Any ideas what i'm doing wrong?
Code is:
<script type="text/javascript">
function getLocationConstant()
   if(navigator.geolocation)
  navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoError); 
   } else {
  alert("Your browser or device doesn't support Geolocation");
// If we have a successful location update
function onGeoSuccess(event)
  document.getElementById("Latitude").value =  event.coords.latitude;
  document.getElementById("Longitude").value = event.coords.longitude;
// If something has gone wrong with the geolocation request
function onGeoError(event)
  alert("Error code " + event.code + ". " + event.message);
</script>
<br><br>
<cfform action="gps2.cfm" method="post">
Latitude: <input type="text" id="Latitude" name="Latitude" value="">
<br><br>
Longitude: <input type="text" id="Longitude" name="Longitude" value="">
<br><br>
<input type="button" value="Get Location" onclick="getLocationConstant()"/>
<br><br>
<input type="submit" value="Add GPS Location" class=small>
</cfform>
I'm guessing it's some kind of XML issue but i have no program language experience at all !!!
Thanks in advance

That code is not for use in a PDF form, but rather an HTML form in a browser. I don't know of any PDF viewers on any device that supports this type of thing.
