Loop counter resets by itself

Hi!

Can anyone explain this? The counter CDR_count should go on forever, but it suddenly resets at every step of the FOR loop (I know this because $_file has exactly 378 records). However, the counter reset is OUTSIDE the FOR loop. What's going on??

Code:
#!/bin/bash

if [ "$1" = "" ] || [ "$2" = "" ]; then
   echo
   echo "USAGE: ./CCN_CDR_parser.sh <CCN CDR files - path & wildcard allowed> <MSISDN>"
   echo
   exit
fi

echo
echo "Searching CDRs for MSISDN $2 in:"
echo "$1"
echo

file_count=0
file_total=`ls -1 $1 | wc -l | tr -d " "`
CDR_count=0
CDR_match=0
echo > CDR.tmp

for _file in `ls -1 $1`
do
  echo -ne "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"\\r
  file_count=`expr $file_count + 1`

     cat $_file | while read _line
     do

             if [ "$_line" = "CDRCCN.ChargingDataOutputRecord.onlineCreditControlRecord" ]; then

                CDR_count=`expr $CDR_count + 1`
                echo "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"

                if [ "`grep "servedAccount : '$2'" CDR.tmp`" != "" ]; then
                   CDR_match=`expr $CDR_match + 1`
                   mv CDR.tmp CDR$CDR_match.txt
                   echo -ne "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"\\r
                fi

                CDR_start="true"
             else
                CDR_start="false"
             fi


             if [ "$CDR_start" = "true" ]; then
                echo $_line > CDR.tmp
             else
                echo $_line >> CDR.tmp
             fi

      done
done

echo
echo

Code:
Files processed: 23 / 1192       CDRs match : 0 / 373
Files processed: 23 / 1192       CDRs match : 0 / 374
Files processed: 23 / 1192       CDRs match : 0 / 375
Files processed: 23 / 1192       CDRs match : 0 / 376
Files processed: 23 / 1192       CDRs match : 0 / 377
Files processed: 23 / 1192       CDRs match : 0 / 378
Files processed: 24 / 1192       CDRs match : 0 / 1
Files processed: 24 / 1192       CDRs match : 0 / 2
Files processed: 24 / 1192       CDRs match : 0 / 3
Files processed: 24 / 1192       CDRs match : 0 / 4

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

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
