Javascript to print and email notes

I too am trying to create a version of what Stephanie did with creating a way for the learner to email feedback to the instructor.  I have a variable called Feedback created in Storyline.  Below is my JavaScript:  I cannot get the variable to populate the body of the email.  I am not fluent in JavaScript.  Can anyone show me where the script is failing?

var player = GetPlayer();
var bodytxt=player.GetVar(“Feedback”);
var mailto_link=’mailto:’+curtis.kynerd@nissan-usa.com+’&body='+bodytxt+"%0d%0A";
win=window.open(mail_link,’emailWin’);
