Hi Nastybutler...

Take a look at my pseudocode, post #5 again.
Your code; there are numerous minor errors and to go through them all before you have solved your project would mean I would be writing it.
Let's get your logic sorted first. You will see from my CODE section how different you logic is from mine.

These lines are fine:
(Just a note, there is no need for the double brackets [[ ]] for this example, single brackets [ ] would suffice. It will still work with double brackets however.)

Code:

#!/bin/bash

counter=0
sum=0

while [[ $counter -le 100 ]]
do
        Important line. "do your arithmetic here which uses both SUM and COUNT"
        Unimportant OPTIONAL print. This can be omitted.
        Important line. "increase your COUNTer by your NEEDED amount"
done
IMPORTANT "print your final value here and should equal the last line of you optional listing"

Again read Don's post #4 thoroughly...

Have another go, and if you increase your "counter" by a certain even number then you will see it all fall into place.
And finally, please use CODE tags, the "</>" icon on the tool bar.

sum

sum(1B) 					     SunOS/BSD Compatibility Package Commands						   sum(1B)

NAME

       sum - calculate a checksum for a file

SYNOPSIS

       /usr/ucb/sum file...

DESCRIPTION

       sum  calculates	and  displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
       look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an  algorithm	which  may
       yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
       been transferred between machines with different-sized ints.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       sum(1), wc(1), attributes(5), largefile(5)

DIAGNOSTICS

       Read error is indistinguishable from EOF on most devices; check the block count.

NOTES

       sum and /usr/bin/sum (see sum(1)) return different checksums.

       This utility is obsolete.
