I have modified the above script to add some error checking and (a little bit more complex to read:-). I hope this is the last time that I have to modify the script, but there is always room for improvement. If you want to use this script to create multiple accounts this is the script for you. It is best used when you have to create multiple users (more than 20 for multiple systems more than 20). The great thing I think this script will tell you if the groups exist or not in the log file /tmp/$HOSTNAME.log. You can also add to the script to delete the log file when it's done.
As I stated before, if you could use the script please do so.

echo > "/tmp/$HOSTNAME.log";echo "[ $TDATE ]" >> "/tmp/$HOSTNAME.log";echo >> "/tmp/$HOSTNAME.log"
