Question Multiple while statements?
I'm working on a script for class as a final project. We have to ask for values (city, state, zip) five times, but the state can only be MI, IN, IL, or OH. I'm trying to do this with a while loop inside of a while loop, but I have no idea how to do it properly.

Here's what I have so far:

Code:
COUNT=0
while [ "$COUNT" -lt "5" ]; do
  clear
  echo "Enter City: "; read CITY
  echo "Enter State: "; read STATE
        while [[ "$STATE" != "MI" && "$STATE" != "IN" && "$STATE" != "IL" && "$STATE" != "OH" ]]; do
          echo "Sorry, that's not an accepted state."; read STATE
        done
  echo "Enter Zip: "; read ZIP
COUNT="$COUNT"+1
done
sleep 5

I have a feeling I'm way off... and I have no idea how to fix it.

Help is appreciated!

itruns

itruns(8)						      System Manager's Manual							 itruns(8)

NAME

       itruns - set up files for use by the it command

SYNOPSIS

       /sbin/itruns file [file...] in run-state [, file [file...] in run-state] [,...]

DESCRIPTION

       The  itruns  program  sets  up scripts to be run by it(8).  (These programs are typically used within system configuration and installation
       scripts.)  The itruns command searches for /sbin/it.d/bin/file. If itruns finds the file, it  creates  one  or  more  symbolic  links  from
       /sbin/it.d/run-state.d/file to /sbin/it.d/bin/file.

       The  run-state  argument can be a single run state, or it can be two run states separated by either the word or or the word and. If two run
       states are specified with the or keyword, itruns checks for (and creates, if necessary) a directory whose name combines both run states and
       places  a link in that directory so that the file will be executed when the it program detects either state.  You can collapse two or-sepa-
       rated states into a single expression; for example, 2 or 3 can be expressed as 23. If the and keyword is used, itruns checks for (and  cre-
       ates, if necessary) two separate directories and places a link in each of them so that either state triggers execution of the file indepen-
       dently of the other state.

       If two or more files are specified for a single run-state argument, links are created for all of the files as indicated	by  the  run-state
       argument.

       If  two or more combinations of files and run states are specified as comma-separated expressions, itruns treats each combination individu-
       ally.

RESTRICTIONS

       The itruns command must be executed from the root directory (/). The command finds only files that are located in the /sbin/it.d/bin direc-
       tory.

EXAMPLES

       This  example  sets  up	the doconfig script to be run when the system is booted to run state 2: itruns doconfig in 2 Either of the command
       lines in this example sets up the doconfig and getdate scripts to be run when the system is booted to run state 2 or to run state 3: itruns
       doconfig  getdate  in  2 or 3 itruns doconfig getdate in 23 This example sets up the doconfig script to be run when the system is booted to
       run state 2 and again when the system comes to run state 3, the getdate script to be run only in run state 2, and the getsysname script	to
       be run only in run state 3: itruns doconfig in 2 and 3, getdate in 2, getsysname in 3
