Fatal Error after editing template

Hello,

I have edited the upload_success.tpl file to change a couple of things, and now I am getting the following fatal error:

"Fatal error: Call to a member function on a non-object in /home/manwire/public_html/videovault/upload_success.php on line 13"

I have tried EVERYTHING I know how to fix this problem. I have re-uploaded the original upload_success.php file (Binary), and the original upload_success.tpl file (ASCII), and I even cleared out the entire templates_c folder, thinking that the system might be referring to the file in there. Nothing works. Now, I cannot upload any videos. I have had other problems after making only minor alterations to .tpl files before in this installation, but I have been able to rectify those somehow. What could be causing this?

Please help.

Thanks,

Scott.
