<p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;
font-family:"Verdana","sans-serif";color:blue'>Well, apparently I was. I had
the duplicate code in the entry frame of lesson 1, so I guess it was executing
each time I moved from page to page in lesson 1? I moved the code to just above
the interface icon (so it can only run once), made the necessary changes to the
childNodes structure, and it was still acting funny. I then found that I had
both a variable and an icon id of 'lesson1Counter' so it's no wonder it was
acting inconsistently. ;o) I fixed that and now I'm consistently getting
the correct number of question nodes.</span><o:p></o:p></p>

<p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;
font-family:"Verdana","sans-serif";color:blue'>I still have one problem though:
it only displays one question. When I get to the first question node, it
displays the question correctly, the second node displays the same question,
and if I back up to the first question node, it's blank. Here is the code
where I get the question number:</span><o:p></o:p></p>

<p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;
font-family:"Verdana","sans-serif";color:blue'>The script icon with this code
is the first icon in the proto Wrap Up page (what I was calling the question
node above), and the proto Wrap Up page is the second child of the
wrap up framework (the Entry Frame being the first child), so questIndex should
be 0 for the first question, and 1 for the next, right? I'm using questIndex+1
for a page counter, and that is correctly displaying 1 for question 1 and 2 for
question 2, but the questions don't change. Any insight on that?</span><o:p></o:p></p>
