Awk variables not printing to StdOutput
Hi guys, I'd be grateful if you could have a look at my code below and give me some feedback as to why the homedir and fullname variables aren't being printed to Standard Output when the script is run. Many thanks.

Code:
read -p "Please type in username you wish to get information from: " username

username="$1"

if grep "$username" information_file
then
   # use awk with -v option to pass in shell variable username to awk. Check if first field $1 is equal to username
   fullname=$(awk -v username="$username" 'BEGIN{FS=":"} $1==username {print $5}' /etc/passwd)

   homedir=$(awk -v username="$username" 'BEGIN{FS=":"} $1==username{print $6}' /etc/passwd)

   # pass the variables to awk. "found" is a toggle flag to signify if user is found. If it is 0, means not found
   awk -v username="$username"  -v homedir="$homedir" -v fullname="$fullname" 'BEGIN{FS=":"; found=0}$1==username
   {
        print "Full name: " fullname
        print "Address: " $2
        print "E-mail address: " $3
        print "Home Directory: " homedir
        print "Manager name: " $5
        found=1
   }' information_file


else
  echo "$username not found in Information File. Exiting.."
  exit 0
fi

service

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

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
