[SOLVED] Having trouble finishing up a bash script

[pauhn]

Basically I have to add a user to the system, full name is upper case in the comment field of the password file, placing them in appropriate groups with a default password of 123456. Username has to be first 5 letters of last name and first letter of first name all lower case. Then I have to be prompted to add another user. I'm not sure if I have the "if then else fi" "while do done" and the "for do done" statements even set up right. This is my first time having to do something like this, and I just want to make sure I have it right.

DECISION=yes
while [ "$DECISION" = "yes" ]
do

echo "Please enter your last name"
read LNAME
echo "Please enter your first name"
read FNAME
echo "Please enter your initial group"
read IGROUP
echo "Please enter any additional groups"
read AGROUP

IGROUPL=`echo $IGROUP | tr [:upper:] [:lower:]`
AGROUPL=`echo $AGROUP | tr [:upper:] [:lower:]`
LNAMEU=`echo $LNAME | tr [:lower:] [:upper:]`
FNAMEU=`echo $FNAME | tr [:lower:] [:upper:]`
USRNM1=`echo $LNAME | cut -c -5 | tr [:upper:] [:lower:]`
USRNM2=`echo $FNAME | cut -c 1 | tr [:upper:] [:lower:]`
USRNM=$USRNM1$USRNM2

useradd -c "$FNAMEU $LNAMEU" -g $IGROUPL -G $AGROUPL $USRNM
echo 123456 | passwd $USRNM --stdin

echo 
"Would you like to add another user?(yes/no)"
read YESNO

DECISION=`echo $YESNO | tr [:upper:] [:lower:]`
DONE

LOOP=1
while [ "$DONELOOP" -eq "1" ]
do
if [ $DECISION == "yes" ]; 
then
DECISION=yes
DONE

LOOP=2
else
if [ "$DECISION" == "no" ]; 
then
echo "Thank you for using this program"
DONE

LOOP=2
else
echo "Please use a correct option. (yes/no)"
read YESNO
DECISION=`echo $YESNO | tr [:upper:] [:lower:]`
fi
done
done
