<DIV dir=ltr align=left><SPAN class=703430319-08122008><FONT face=Verdana
color=#0000ff size=2>Maybe I'm just going about this entirely the wrong way.
What I want to accomplish is to have all my test questions within one setup.xml
file. I have six lessons, and some of the questions will also be presented at
the end of each lesson. So I need to parse which questions are for lesson 1,
which are for lesson 2, etc. Once the student has completed all of the lessons,
they must take a test to pass the course. This test will be comprised of all of
the questions for all of the lessons, with the questions randomized. Am I on the
right track with what I've been trying to do, or do I need to take a different
approach?</FONT></SPAN></DIV>

<P class=MsoNormal style="MARGIN-LEFT: 36pt"><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'">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></P>

<P class=MsoNormal style="MARGIN-LEFT: 36pt"><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'">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></P>

<P class=MsoNormal style="MARGIN-LEFT: 36pt"><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: 'Verdana','sans-serif'">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></P>
