KSH Shell script not zipping up files

Question

I have a Korn shell script that is supposed to zip up files and it is not working properly in development. The same exact script works in production which is strange. We recently upgraded our Solaris Unix box to a Linux box in the development environment. So I am assuming that this may be the cause of the script not executing.

The pic below is shows the file list. The user will select a checkbox for the files they want to download and then they click the zip and download link and it should zip up those selected files and save it to your desktop. Unfortunately the zip folder is empty. Any ideas what the problem may be?

Here is the code below that zips up the files. Any idea why this Korn shell script works in development but not in production?

#!/bin/ksh
#
# Utility to zip up files in the configuration_aerodynamic_properties area.
# Script takes two arguments the directory and the file list.
# The file list is tab seperated.
# This script returns the zip file.

@meuh I removed the - in the set -A FILE_LIST -, here are the results of the error logs from our server. What does this mean because the txt files that I selected to zip and download to my desktop are still not saving to the zip folder. Here are the results below:
