Send correct exit code from child script back to parent

Hello all; hope someone can help me cause I am going crazy trying to find a solution for (what I think is simple) issue...looked hard up and down this forum and tried several "solutions" with no avail...so here's my issue:

I have this (parent) script: copylsofdcmcadefttosftpwithmove.sh

Inside this script I have this piece of code:
Code:
if [ "$flag" = "yes" ]
then
        /usr/local/bin/ssh $sftpserver mv $sftppath/$filenameshort $finaldirname  >> ${_ftpdebug} 2>&1
        ssh faunus:/home/dslmain/scripts/senddcmcadefttest.sh
        if [ $? -ne 0 ]
        then
           echo "EXIT: " $?
           exit
        fi
        echo "DONE"
else
        echo "FAILED"
fi

I call another script via ssh (red text).

This is the contents of the script: senddcmcadefttest.sh
Code:
#!/bin/sh -x
node=fid
NODE=FAUNUS
_Ymd=`date +%Y%m%d`
indir=/home/dslmain/export/${node}/eft/in
sentdir=/home/dslmain/export/${node}/eft/sent
LOG="/home/dslmain/export/$node/eft/logs/eft.log.`date +%m%d`"
_temp=/utemp/tmp_logs/eftexists
if [ -s $_temp ]
then
  rm $_temp
fi
_ym=`date +%m%d`

ls ${indir}/*${_ym}* > $_temp
if [ ! -s $_temp ]
then
   echo "No EFT files detected" >> ${LOG}
   exit 1
fi
cd ${indir}
for FILE in `cat $_temp|awk -F'/' '{print $NF}'`
do
  if [ -s ${FILE} ]
  then
    echo "Here _UPLOAD function would have run"
    echo "Snapshot of files of the day found on RBC FTP" >> ${LOG}
    A=1
    B=1
    echo $A >> ${LOG}
    echo $B >> ${LOG} 
    if [ ${A} -eq ${B} ]
    then
      echo "${FILE} was successfully uploaded to RBC" >> ${LOG}
      echo ""  >> ${LOG}
      mv ${indir}/${FILE} ${sentdir}/${FILE}
      exit 0
    else
      echo "${indir}/${FILE} failed to be loaded to RBC" >> ${LOG}
      echo " "  >> ${LOG}
      exit 2
    fi
  else
    echo "Sorry file dose not exist, or file is empty" >> ${LOG}
    exit 3
  fi
done

So in the child script I have 3 different scenarios (in red) where the exit code will be either 0, 2 or 3...I want to pass the correct exit code back to the parent script
copylsofdcmcadefttosftpwithmove.sh so that it can be evaluated in the "if" statement...however $? is always coming back as "0"...

Thanks for reading and any assistance.

Regards
Giuliano
