Trouble with Nested Ifs
What I thought was going to be very simple has turned out to be really lame, and so I come to you for help.

Code:
mountedon=`df -k /synctest | awk 'NR == 2 {print $1}'`
if [ $mountedon -ne "ids4:/nex02/synctest" ]
then
   # mount /pupcl06
   mountedon=`df -k /synctest | awk 'NR == 2 {print $1}'`
   if [ $mountedon -ne "ids4:/nex02/synctest" ]
   then
      mailx -s "nightly sync FAILED - check drive mountings" name@email.com name2@email.com << EOH
         drive 'synctest' is not mounted properly.
      EOH
      echo mounting error
      break
   else
      echo successfully mounted
      # wmsynctest
   fi
else
   echo was previously mounted
   # wmsynctest
fi
echo yerp

Note: lines are commented out because I don't want this to actually do anything yet.

Basically, I'm trying to check to see if a drive is mounted properly. If it is, execute another script. If not, try to mount it. If that fails, kill the process. If it succeeds, execute another script.

When I run this program, I get an unexpected end of file error. I'm assuming it's related to the nested ifs because of similar errors I read about online.

So if you know how to get around this problem with the ifs, please let me know. Thank you.

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

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.
