Why doesn't this loop end?

Simple script, takes an cmd line argument and counts down to 1.

Code:
NUMBER=$1
# One argument must be provided, otherwise don't execute
if [ $# != 1 ]
then
    echo "Error. Enter one argument "
    exit 0
elif [ $# == 1 ]
then
        echo " "
fi
# Integer value must be greater than zero
while [ $NUMBER > 0 ]
do
   echo "$NUMBER"
# If the value of the argument is greater than one, insert a comma after the integer
   if [ $NUMBER > 1 ]
   then
     echo ", "
fi
# Decrease the value of NUMBER by one with each iteration
NUMBER=$(($NUMBER - 1))
done
echo "$NUMBER"

two issues I am working, the first is that the loop does not end, it keeps counting down forever. The second problem, I don't want each # and , on a newline, I want them all on the same. I did this in PERL and it works fine, now I need to write it as a bash script having issues.
