Logging and tracking quiz results to a web server

Hello, I'm working towards the goal of using javascript to post quiz results to a web server. I'm starting small by simply using console.log to log quiz results, this this small test is not working. Can someone guide me in the right direction please? My script is below, and it executed by trigger when timeline (results slide) starts. Thanks!

var player = GetPlayer();
var score = player("Results.PassPercent");
console.log("score");
