Can someone please help!

Hi!
I am trying to write a little script here, which would take input from the user and store them in arrays. But the array part is not working for some reason.

Can anyone help please.

Code:
#!/usr/bin/sh
##Take input from the user
while [ host_name != "."]
do
  echo "Please enter the host_name"
  read host_name
  echo "host_name is $host_name"
  store_hostname[$c]=$host_name
  c=$(( c + 1 ))
  echo "Please enter the username"
  read username
  echo $username
  store_username[$d]=$username
  d=$(( d + 1 ))
  echo "Please enter the password"
  read password
  echo $password
  store_password[$e]=$password
  e=$(( e + 1 ))
done

#Create a destination directory
ssh $store_host_name[c] mkdir temp
#scp files to host
scp -r /root/temp $store_username[c]@$store_host_name[c]:/root/

NAME
ppmtosixel - convert a portable pixmap into DEC sixel format SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC LJ250 color inkjet printer. If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file. OPTIONS
-raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com- pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni- tude larger than a compressed file and prints much slower. -margin If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci- fied, a 1.5 inch left margin will offset the image. PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?. BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation. SEE ALSO
