[all variants] Bash script error

http://ubuntuforums.org – I'm posting this in hopes that someone can help me solve my dilemma. I have created a script which I found in the following link: http://www.labnol.org/software/print...n-linux/17841/ This is supposed to enable moving a file to a Dropbox folder named PrintQueue and then have it sent to a remote printer when the script runs. The script is giving me problems. I have attached the script and also a screen print of the error message that I receive whenever I attempt to run the script. If anyone can see what is wrong with this script, I would greatly appreciate any assistance in resolving the pro (Hardware)
