Error when I do exercise about Learn Bash and SQL by Building a Bike Rental Shop - Build a Bike Rental Shop

I try to do exercise about Learn Bash and SQL by Building a Bike Rental Shop - Build a Bike Rental Shop until the exercise: Move the echo command that prints all the available bikes below the message you just added, i try do add echo "$AVAILABLE_BIKES", it was true but I try to click Run to pass it was error many times: `. I tried to reset many times and do again but was error many times.

Here is my source code:

#!/bin/bash

PSQL="psql -X --username=freecodecamp --dbname=bikes --tuples-only -c"

echo -e "\n~~~~~ Bike Rental Shop ~~~~~\n"

MAIN_MENU() {
  if [[ $1 ]]
  then
    echo -e "\n$1"
  fi

  echo "How may I help you?" 
  echo -e "\n1. Rent a bike\n2. Return a bike\n3. Exit"
  read MAIN_MENU_SELECTION

  case $MAIN_MENU_SELECTION in
    1) RENT_MENU ;;
    2) RETURN_MENU ;;
    3) EXIT ;;
    *) MAIN_MENU "Please enter a valid option." ;;
  esac
}

RENT_MENU() {
  # get available bikes
  AVAILABLE_BIKES=$($PSQL "SELECT bike_id, type, size FROM bikes WHERE available = true ORDER BY bike_id")
  echo "$AVAILABLE_BIKES"

  # if no bikes available
  if [[ -z $AVAILABLE_BIKES ]]
  then
    # send to main menu
    MAIN_MENU "Sorry, we don't have any bikes available right now."
  else
    # display available bikes
    echo -e "\nHere are the bikes we have available:"
    echo "$AVAILABLE_BIKES"
    # ask for bike to rent

    # if input is not a number

    # send to main menu

  fi
}

RETURN_MENU() {
  echo "Return Menu"
}

EXIT() {
  echo -e "\nThank you for stopping in.\n"
}

MAIN_MENU

You have copied the echo command to the correct place, but you also need to delete the original echo command (i.e. it should be moved rather than copied).

Shopify is a good ideal for a service provider to start an online bike shop. In addition, there are also platforms that provide the POS system and other things you will need.

i am curently facing the same issue, have you managed to solve it? how did you do it?
