I'm using this code to change direction line color in google map v2, but still it won't work even after using getpolyine? How can I change it?

` function direction() {

    var txtAddress = document.getElementById("<%=txtAddress.ClientID %>");

    var address = txtAddress.value;

    var TextBox1 = document.getElementById("<%=TextBox1.ClientID %>");

    var address1 = TextBox1.value;

    directions = new GDirections(map, directionsPanel);
    directions.load("from: " + address1 + " to: " + address + "", { getPolyline: true });
    setTimeout(handle, 1000);
  //  var address =txtAddress.value + "  " + TextBox3.value;

}
function handle() 
{
    var points = [];
    var poly = direction.getPolyline();
    for (var i = o; i < poly.getVertexCount(); i++) {
        points[i] = poly.getVertex(i);
    }
    var mypoly = new GPolyline(point, "#ff627", 3, 1)
    map.addOverlay(mypoly);
 }
