expr not working

I have written below script which monitors a log file and if log file is not writting for 2 intervels then admin should be notified.

================

Code:

sh=`date | awk '{print $4}' | cut -d ":" -f1`
sm=`date | awk '{print $4}' | cut -d ":" -f2`
lh=`ls -l /opt/Heartbeat.log | awk '{print $8}' | cut -d ":" -                                              f1`
lm=`ls -l /opt/Heartbeat.log | awk '{print $8}' | cut -d ":" -                                              f2`
if [ "$sh" = "$lh" ]
then
  if [ "$sm" = "$lm" ]
  then
    echo "Database written properly"
  else
    echo "Database failed to written"
    echo $x
    x=`expr $x + 1`
    echo $x
    if [ "$x" = "2" ]
    then
      mailx -s "Data base failed written - Need to retrieve missing data" -c "abc@xyz.com"<<EOF
    else
      echo "Hello"
