Q:

Random Google Maps Marker from Array

I am trying to add a custom marker from an array on Google Maps I have seen another question close to this but the code provided doesn't allow Google Maps API to pick the Marker Icon 
 function button1(location) {
var get1 = prompt ("Enter First Coord");
var get2 = prompt ("Enter Second Coord");

var icons = [
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_green.png",
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_purple.png",
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_orange.png",
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_white.png",
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_black.png",
"https://raw.githubusercontent.com/Concept211/Google-Maps-Markers/master/images/marker_blue.png"

];
var items;
var center = new google.maps.LatLng(get1,get2);
map.panTo(center);
var marker = new google.maps.Marker({
position: center,
map: map,

icon: items[Math.floor(Math.random()*icons .length)]
});

I keep getting a "items is not defined".
If I define it above the code I get a different error saying 
"Cannot read property '3' of undefined" on the icon: items[Math.floor(Math.random()*icons .length)] code
If anyone knows the solution I would very much appreciate it, thanks!

A:

You are trying to get content of empty variable items... Replace
icon: items[Math.floor(Math.random()*icons .length)]

with:
icon: icons[Math.floor(Math.random()*icons .length)]

Because you haven't got saved pictures in variable items but in variable icons.
