you should use (( )) for numerical operations i.e.
Code:
while read -p  "Enter Schema Name $((cnt + 1)): " schemaname
do
    arry[cnt]=$schemaname

    wnt2prc=""
    while [ "$wnt2prc" != "n" ] && [ "$wnt2prc" != "y" ]
    do
       read -p "Want to proceed (y/n): " wnt2prc
    done

    (( cnt++ ))
    if [ $wnt2prc = "n" ] || (( cnt > 2 ))
    then
       if (( cnt > 2 ))
       then
            echo "Maximum schema number (3) reached"
       fi
       break
    fi
done

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

NAME

       checksecurity - Run a collection of simple system checks

SYNOPSIS

       checksecurity

DESCRIPTION

       The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues.  check-
       security is run by cron in a daily basis.

CONFIGURATION

       The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR.  Each is
       described below.

       The  checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
       by their own configuration file.

       CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked.  This script is designed to report upon  system  accounts
       which  have  no passwords.  CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
       be sent if there is any mounted partition is running short on disk space.  CHECK_SETUID If this is set to TRUE then the check-setuid script
       will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.

FILES

       /etc/checksecurity.conf
	      checksecurity configuration file

       See also check-diskfree(8), check-setuid(8), and check-passwd(8)
