Please modify your if-else statement like below and re-try:-

Code:
if [ `ps -eaf | grep -v grep | grep -c $CHECK_SCRIPT` -ne 0 ]
then
      logger -s "$CHECK_SCRIPT is running. Do nothing"
else
      logger -s "$CHECK_SCRIPT is not running. Please restart script"
fi           

if [ `pgrep -l $SERVICE | grep -c $SERVICE` -ne 0 ]
then
      logger -s "$SERVICE process is running. Do nothing"
else
      logger -s "$SERVICE process is not running. Please restart service"
fi

@bipin, thank you so very much
that did it!

just in case if anyone needs a script that checks if itself is running/not running as well as the process its meant to check if its running/not running

Code:
#!/bin/bash
SERVICE="httpd"
CHECK_SCRIPT="/usr/local/bin/test"

if [ `ps -eaf | grep -v grep | grep -c $CHECK_SCRIPT` -ne 0 ]
    then
logger -s "$CHECK_SCRIPT is running. Do nothing"
    else
logger -s "$CHECK_SCRIPT is not running. Please restart script"
    fi

if  [ `pgrep -l $SERVICE | grep -c $SERVICE` -ne 0 ]
    then
logger -s "$SERVICE process is running. Do nothing"
    else
logger -s "$SERVICE process is not running. Please restart service"
    fi
