Linux Script Nested if-statements giving syntax error - linux

Question

I am trying to nest multiple if-statements as the following:
#!/bin/bash
# start_server.sh
#
# Use this script to start the MarketDataTransmitter.
#
# Usage: ./start_server.sh Starts the MarketDataTransmitter.
reset=$(tput sgr0)
red=$(tput setaf 1)
green=$(tput setaf 2)
yellow=$(tput setaf 3)
cyan=$(tput setaf 6)
echo
directory=$(ls -l)
check_exist=$(awk -v a="$directory" -v b="MarketDataTransmitter" 'BEGIN { print index(a, b) }')
if [ "$check_exist" = "0" ]; then
# MarketDataTransmitter is not present.
echo "${red}[ERROR]${reset} Could not start ${yellow}MarketDataTransmitter${reset}."
echo " ${yellow}MarketDataTransmitter${reset} could not be found."
else
# MarketDataTransmitter is present.
processes=$(ps -ef | grep -i "MarketDataTransmitter" | grep -v "grep" | grep -v "bash" | awk '{ print $8 }')
check_run=$(awk -v a="$processes" -v b="MarketDataTransmitter" 'BEGIN { print index(a, b) }')
if [ "$check_run" = "0" ]; then
# MarketDataTransmitter is not running.
if [ -e "srv.log" ]; then
if [ -s "srv.log" ]; then
if [ -d "logs" ]; then
date_time=$(date '+%Y%m%d_%H_%M_%S')
new_log_name="srv_$date_time.log"
mv srv.log $new_log_name
mv $new_log_name logs
else
mkdir logs
date_time=$(date '+%Y%m%d_%H_%M_%S')
new_log_name="srv_$date_time.log"
mv srv.log $new_log_name
mv $new_log_name logs
fi
else
echo "srv.log is empty and will be removed."
rm -rf srv.log
fi
else
# No srv.log but this is to start MarketDataTransmitter so we can ignore.
fi
./MarketDataTransmitter > srv.log &
echo "${yellow}MarketDataTransmitter${reset} has been started."
else
# MarketDataTransmitter is already running.
echo "${red}[ERROR]${reset} Could not start ${yellow}MarketDataTransmitter${reset}."
echo " ${yellow}MarketDataTransmitter${reset} is already running."
fi
fi
echo
However it is giving me syntax complaints saying:
syntax error near unexpected token `fi'
on the very last 'fi'
Does anyone know why?
Thanks.
[EDIT] Full code has been posted.

You have an else statement and fi statement with nothing between them on lines 44-46 (just a comment between them). In bash, you need to have some statement in the body of that else block, or take the else block out.
