I want to print a certificate at the end of  my module which displays the student name and their score. I have effectively been able to get the user name and scoreon the certificate. When I publish and do not zip the file, it works beautifully. When I zip it and send it someone for testing, the certificate will not show up.  I have tested this out several times. If the file is zipped at any point and then unzipped in order to access the index file to play it, it does not show up. it shows loading and then a white screen shows up. anyone have any ideas?
