Prevent back browser button script interfering with variable on page

Hi all! I've disable the back browser button in my course for the final test so they can't go back and change the answers. However, if the student passes the test, the course takes them to a page to print a customized certificate of completion. When I add the HTML meta-tag to that page, it prevents the student name from appearing on the certificate. Any ideas/suggestions?


Thanks in advance,

Dawne
