Embed Java/Flash Quiz

I am trying to embed a java/flash quiz into posts or pages but it freezes. The quiz is working here:
https://www.jeeppilot.com/IMIT_files/quizme.html
but here it locks up:
https://www.jeeppilot.com/?page_id=4

This is the code I added:

<script language=”javascript” src=”/IMIT_files/swf.js”></script>
<center>
<script language=”javascript”>
<!–
writeSwf(“/IMIT_files/quizme.swf”, 720, 540);
//–>
</script>
</center>

and I also tried the [ include_me_in_that_html ] plugin with weird results here:
https://www.jeeppilot.com/?p=5

I have the feeling I am doing something wrong but cannot find anything related in this forum.

Thanks for any suggestions.
