That makes sense. I will check my server's error log to see if there is any mention of this error.

Having error messages printed to the browser would have saved me from posting my careless mistake. :) I'll start using CGI::Carp qw(fatalsToBrowser warningsToBrowser) to help check my code. Although I do recall compling this bit of code from the command line using perl -c upload.pl and it simply responded with perl syntax OK.

Thanks
