Java Script Help - email user input

Hi guys, looking for Java script advice. I want to create an activity in SL2 where the user types in free form fields and their input is emailed for evaluation (see attached image of screen).

Based on a previous post, I adapted the following Java script for my trigger. Not working - email icon with trigger does nothing. Appreciate your help!

Rick

var player = GetPlayer();

var useremail=player.GetVar("email");

var subject="Partnership Opportunities";

var exercisenotes1=player.GetVar("entryRef1");
var exercisenotes2=player.GetVar("entryRef2");
var exercisenotes3=player.GetVar("entryRef3");
var exercisenotes4=player.GetVar("entryRef4");
var exercisenotes5=player.GetVar("entryRef5");

var mailto_link='mailto:'+useremail+'?subject='+subject+'&body=
'+"Activity Notes - My partnership opportunities:“
+exercisenotes1+"Contact 1“
+exercisenotes2+"Contact 2“
+exercisenotes3+"Contact 3"
+exercisenotes4+"Contact 4“
+exercisenotes5+"Contact 5";

win=window.open(mailto_link,'emailWin');
