I am trying to direct multiple polylines to a particular marker in a map.
I am able to draw the polylines to the marker but when I try to animate the same only the last polyline is working. The link below shows the map I made.

Also this is the code:
<html>
<head>
<style type="text/css">
html {
height: 100%
}
body {
height: 100%;
margin: 0;
padding: 0

#map_canvas {
height: 100%
}
</style>

Could anyone help me fixing this problem. Thanks in advance.
Make an array to hold all your polylines:
var lines = [];
push your existing line(s) on that array:
lines.push(line);
Process through them updating the icons.
function animate(){
var count = 0;
offsetId = window.setInterval(function(){
count = (count + 1) % 2000;
for (var i=0; i<lines.length; i++) {
var icons = lines[i].get('icons');
icons[0].offset = (count / 2) + '%';
lines[i].set('icons', icons);
}
}, 200);
}// end of animate function
