The permissions on running.pdf was not correct. It helps if you know how to debug!
Talking about debugging... You should get the habit of including:
   use strict;
   use warnings;
in the beginning of every Perl program you write. (They would not have
made a difference to solve this particular problem, but they may do so
next time.)
Yes, I tend not to do that.... Makes my code look beter when it runs......... Just fooling myself I guess.


You are, and beauty is in the eye of the beholder, your code may look
better to you, but to the computer it definitely doesn't.  Perfect
example, given,

open(test123, ">>/home/staff/wot/public_html/perl/test.csv") or die
("File test.csv could not be opened for writing");

What do you think the following three lines do?

flock(test, 2);
seek(test, 0, 2);

close(test);

Or how about your error conditions,

or die "Error adding $file_gif: $!\n";
or die "Error adding $file_zip: $!\n";

So much for including the filename.

'strict' and 'warnings' will save you hours of headache.

When I include warnings and strict is give me allot of warnings. What do they mean?
