Error Read 2 $vars from file line by line

Need some help with the following Bourne Shell script. The script is only looping one time and then stops. The script should loop as many times as there are entries in the input file = $FILE_LIST line by line. The file has the path to a source file and the destination directory where the file should be put. The script is transferring the files okay, now I want to make sure the entire file transferred using the chksum command, if so then delete the file off of server "B"

The FILE_LIST has the following data:

/home/test/test.pdf /home/test
/home/test/test.pdf /home/test
/home/test/servers_test /home/test
/home/test/test2842.pdf /home/test
/home/test/test.rpm /home/test

I would expect 5 lines of output, but my results is only giving me the first line. Here is the portion of the script that should delete the 5 files listed in the FILE_LIST file from server "B"

DID_NOT_TRANSFER=/tmp/FILES_DID_NOT_TRANSFER
FILE_LIST=/tmp/src_test
touch $DID_NOT_TRANSFER

while read SRC_FILES DEST_DIR
do
# Check to see if the entire file made it over using the cksum command
CHKSUMFTP=$(ssh test-ftp cksum $SRC_FILES |awk '{print $1}')
CHKSUMAPPS=$( cksum $DEST_DIR/`/usr/bin/basename $SRC_FILES`| awk '{print $1}')
# Check the value of the checksums from both servers
if [ "${CHKSUMFTP}" = "${CHKSUMAPPS}" ] ; then
ssh test-ftp /bin/rm ${SRC_FILES}
else # Save the file name in a temp file to be mailed out later
echo $SRC_FILES >> $DID_NOT_TRANSFER
echo " \n" >> $DID_NOT_TRANSFER
fi
done < $FILE_LIST
mailx -s "SRC_FILES did not transfer to apps properly on `date`" < $DID_NOT_TRANSFER maillist
/bin/rm $DID_NOT_TRANSFER
exit 0

continue(3tcl)						       Tcl Built-In Commands						    continue(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(3tcl), for(3tcl), foreach(3tcl), return(3tcl), while(3tcl) KEYWORDS
continue, iteration, loop Tcl continue(3tcl)
