Sorry guys I'm a rookie on JS and I have the problem explained below: how do I pass the values of vars "lat1" and "long1" to outside the function and assign them to wp[0] as shown?

(No problem with wp[1] that I get from another file).

Thanks,

Miguel

Code:
<script type="text/javascript">
	
	navigator.geolocation.getCurrentPosition(
 	function (pos){
        lat1 = pos.coords.longitude;
	long1 = pos.coords.latitude;
});
	var lat2 ="<?php echo $_SESSION['lat']; ?>";
	var long2 ="<?php echo $_SESSION['long']; ?>";	
	
         var wp = new Array(2);
	 wp[0] = lat1 + "," +long1;
	wp[1] = lat2 + "," +long2;
	
	inicio = (wp[0]);
	destino = (wp[1]);
