Mailto Question

Hi everyone!

I would like to know how to pass the percGlobal variable that I created in the for loop into the body of the email that is created in the function below. Right now all it prints in the body of the email is: 

percGlobal + percent

Thanks!

var nScore:Number = 0;
var nTotal:Number = 0;
var nPercentage:Number = 0;

for(var i:Number = 0; i < aQuestions.length; i++)

{
var percGlobal;
     this["userAnswer" + i + "_txt"].text = aUserAnswers;
     this["correctAnswer" + i + "_txt"].text = aCorrectAnswers;
     if(aUserAnswers.toUpperCase() == aCorrectAnswers.toUpperCase())
     {
          nScore++;
   
     }
     if(i == aQuestions.length - 1)
     {
          score_txt.text = nScore.toString();
     }
  nTotal++;
  correct_txt.text = nScore.toString();
  total_txt.text = nTotal.toString();
  percGlobal = Math.round((nScore/nTotal)*100).toString();
  percentage_txt.text = percGlobal + "&" ;
}

shareBtn.addEventListener(MouseEvent.CLICK, onShare);
function onShare(event: MouseEvent) {
var request:URLRequest = new URLRequest("mailto:robert.hannan@bcbsfl.com"+"?subject=Quiz Score"+"&body= percGlobal + percent");
navigateToURL(request, "_self");
}
