##Validating if all inputs were entered
echo "Entering the program `date`" 																				
if [ $# -ne 10 ]
then
echo "One or more inputs to this program were not entered." 													
echo "Please verify the Appworx module" 																		
echo "Aborting the program on `date`"																			
exit 1
else
echo "All inputs to this program have been entered" 															
fi

As greet_sed and I have both pointed out, does any one or more of these paramters have whitespaces
in them without quotes or NULL values?

Possible ones are:-
Code:
USERNAME="$1"
LOCAL_DIRECTORY="$3"
REMOTE_DIRECTORY="$4"
LOG_FILEPATH="$6"
LOG_FILENAME="$7"
BIN_PATH="$8"
LOCAL_JOBNAME="$9"
REMOTE_JOBNAME="$10"

Example longhand OSX 10.7.5 default bash terminal:-
Code:
