Shell Programming and Scripting

I'm a begginer with scripting...

Have a script that pulls check information data. There are multiple lines for each check. ALL the info is the same on the line EXCEPT the charges. ie: same check number, same payee, same patient, same check date, DIFFERENT CHARGE. I need to total the charges for the each check number ( there may be 1 line per check number, or 15 lines per check number depending on how many charges there are) and combine the like info to have 1 line per check with the total amount of all the charges. Copy of existing script that pulls the data:

# reformat the luminator report camden to send a check register
# 11/07/05 dvh written
#
# run by entering - camden.sh DATE
#

if [ "$1" = "" ]; then
echo " "
echo " Usage: camden.sh <MMDDYY>"
echo " PRESS ENTER TO CONTINUE..."
read reply
exit 1

Thanks for any help. The first column is the check number, the last is the charge. This is not all the data and IT IS formated in positions. ALL FIELDS ARE IN SAME POSITIONS. I just need to know how to do this.
