`if' is not matched

I am getting the below error when trying to execute the script ./LIFNR_error_alert.s

./LIFNR_error_alert.sh[8]: 0403-057 Syntax error at line 14 : `if' is not matched.

Code :

has_error_occured=false
if [ $current_interval_count -gt $last_interval_count ]
then
has_error_occured=true
new_error_count=$((current_interval_count - last_interval_count))
fi
if [ $has_error_occured ];then
    grep 'Required input field LIFNR' /data/logs/errorWMS-SAP_LV_20_02.log > /u/peima01/LIFNR_alert/script/all_errors_in_file.txt
    tail  -$new_error_count /u/peima01/LIFNR_alert/script/all_errors_in_file.txt > /u/peima01/LIFNR_alert/script/errors_to_mail.txt
    cat /u/peima01/LIFNR_alert/script/Template.txt > /u/peima01/LIFNR_alert/script/mail_body.txt
    cat /u/peima01/LIFNR_alert/script/errors_to_mail.txt >> /u/peima01/LIFNR_alert/script/mail_body.txt
    (cat /u/peima01/LIFNR_alert/mail_body.txt)| mail -s "List of Vendors not receiving IDOC" xyz@gmail.com
else
    echo " No errors logged" xyz@gmail.com
fi
