Titolo: Why won't cookie value show up?

Used one of these canned scripts to set up a JS quiz but not before having
used another canned PHP script for "Tell your friend about this Web page!"
sort of thing. Now i've gotta integrate them; client wants the results from
the quiz to go into the email.
The file "quizconfig.js" parses the form-submitted test results & the test
results page (quiz1_results.htm), in turn,  shows the score. The JS in the
quizconfig.js appears to set a cookie from which quiz1_results gets the
calculated score. So I pasted all the same JavaScript that appears in the
quiz1_results page into the "Tell your Friend" page in an attempt to be able
to tweak the (PHP-based) email body to contain the variable that holds the
results.
I keep getting "Undefined" for the value of the variable. Can't figure out
what I might be doing wrong.
the source code of "quizconfig.js" is here (between line of asterisks):
*****************************************
//Enter total number of questions:
var totalquestions=10
//Enter the solutions corresponding to each question:
var correctchoices=new Array()
correctchoices[1]='b' //question 1 solution
correctchoices[2]='b' //question 2 solution, and so on.
correctchoices[3]='c'
correctchoices[4]='a'
correctchoices[5]='a'
correctchoices[6]='c'
correctchoices[7]='c'
correctchoices[8]='b'
correctchoices[9]='c'
correctchoices[10]='b'
/////Don't edit beyond here//////////////////////////
function gradeit(){
var incorrect=null
for (q=1;q<=totalquestions;q++){
 var thequestion=eval("document.myquiz.question"+q)
 for (c=0;c<thequestion.length;c++){
  if (thequestion[c].checked==true)
  actualchoices[q]=thequestion[c].value
  }
 if (actualchoices[q]!=correctchoices[q]){ //process an incorrect choice
  if (incorrect==null)
  incorrect=q
  else
  incorrect+="/"+q
  }
 }
if (incorrect==null)
incorrect="a/b"
document.cookie='q='+incorrect
if (document.cookie=='')
alert("Your browser does not accept cookies. Please adjust your browser
settings.")
else
window.location="quiz1_results.htm"
}
function showsolution(){
var win2=window.open("","win2","width=200,height=350, scrollbars")
win2.focus()
win2.document.open()
win2.document.write('<title>Solution</title>')
win2.document.write('<body bgcolor="#FFFFFF">')
win2.document.write('<center><h3>Solution to Quiz</h3></center>')
win2.document.write('<center><font face="Arial">')
for (i=1;i<=totalquestions;i++){
for (temp=0;temp<incorrect.length;temp++){
if (i==incorrect[temp])
wrong=1
}
if (wrong==1){
win2.document.write("Question
"+i+"="+correctchoices[i].fontcolor("red")+"<br>")
wrong=0
}
else
win2.document.write("Question "+i+"="+correctchoices[i]+"<br>")
}
win2.document.write('</center></font>')
win2.document.write("<h5>Note: The solutions in red are the ones to the
questions you had incorrectly answered.</h5><p align='center'><small><a

win2.document.close()
}
*************************************
The (canned) JS used in the search results page is here (or if you take the
test & get the results page at 
http://www.smoochya.com/quiz1.html
 you can
see it):
***************************************
<script src="quizconfig.js">
</script>
<script>
var wrong=0
for (e=0;e<=2;e++)
document.result[e].value=""
var results=document.cookie.split(";")
for (n=0;n<=results.length-1;n++){
if (results[n].charAt(1)=='q')
parse=n
}
var incorrect=results[parse].split("=")
incorrect=incorrect[1].split("/")
if (incorrect[incorrect.length-1]=='b')
incorrect=""
document.result[0].value=totalquestions-incorrect.length+" out of
"+totalquestions
var numberright=totalquestions-incorrect.length
document.result[2].value=(totalquestions-incorrect.length)/totalquestions*10
0+"%"
for (temp=0;temp<incorrect.length;temp++)
document.result[1].value+=incorrect[temp]+", "
</script>
***********************************
From a hyperlinked image within the same search results page........
<a href="JavaScript:newWindow('tellafriend_quiz1.php')"><img
src="/images/passitalong_quiz.jpg" border="0"></a>
...........I have it open a new window for the "Tell a friend" using
this....
function newWindow(tellafriend){
 tellafriendwindow = window.open(tellafriend, 'tellwin',
'width=550,height=350')
 tellafriendwindow.focus()
 }
Within the "Tell A Friend" PHP page (http://, I have the same JS as what's
in the search results:
<script src="quizconfig.js">
</script>
<script language="javascript">
var wrong=0
for (e=0;e<=2;e++)
document.result[e].value=""
var results=document.cookie.split(";")
for (n=0;n<=results.length-1;n++){
if (results[n].charAt(1)=='q')
parse=n
}
var incorrect=results[parse].split("=")
incorrect=incorrect[1].split("/")
if (incorrect[incorrect.length-1]=='b')
incorrect=""
document.result[0].value=totalquestions-incorrect.length+" out of
"+totalquestions
var numberright=totalquestions-incorrect.length
But when I'm using this "numberright" variable in an alert to tell me
whether or not i know what the hell I'm doing ....
<script language="javascript">alert("You got " + numberright + "
right!")</script>
......it doesn't work.
the pages involved can be seen at 
http://www.smoochya.com/quiz1.html
 I feel
like I'm almost there but I can't seem to get the value of the number right
to persist through to the tell-a-friend page.
Any suggestions?
Thanks in advance!
