Isn't a shell found on a beach? Need help nesting if's or loops.

As of a week ago i thought a shell was somthing found on a beach.

I'm a virgin when it comes to scripting and i'm having a really bad time here.

What i need to do is prompt for a group number
grep the /etc/groups to get the GID and name

if it exists i want to prompt the user for comfirmation to add user to the group (the other part of the script...thats working) while dispalying the group name and id.

if not i want to promt the user to make a group with name and id supplied by user input via promts.

this is what i have so far.

Sorry for being such a noob.
Code:
#!/bin/bash
 
echo
echo "User ID?"
echo
read INPUT
 
TEMPIN=$INPUT;
 
TEMPTN=`grep ":${TEMPIN}:" /etc/group |cut -d: -f3`;
 
TEMPST=`grep ":${TEMPIN}:" /etc/group |cut -d: -f1`;
 
echo "True number ${TEMPTN}"
echo "True String ${TEMPST}"
echo "Input ${TEMPIN}"
 
if [ $TEMPNT==$TEMPIN ]; then
 
 
           echo  
           echo "GID        : ${TEMPTN}"
           echo "Group name : ${TEMPST}"
           echo
           echo "Already exists, do you want to use this group"
           echo
           echo "<y> or <n>"
           read INPUT
 
                 echo        
                 if [ ! $INPUT = "n" ]; then
                 GROUP_ID=${TEMPIN};
                 fi
fi
 
if [ ! $TEMPNT==1$TEMPIN ]; then
 
 
     echo
     echo "Group ID ${TEMPIN} does not exist"
     echo "would you like to create it?"
     echo
     echo "<y> or <n>"
     echo
     read INPUT
     echo
           if [ ! $INPUT = "n" ]; then
                 echo
                 echo "Enter group name"
                 read NAME
                 echo              
                 GRP=$NAME;
                 GID=$TEMPIN;
 
                       else
                       echo "Setup cannot contine without a specified group!"
                       exit
           fi
fi
