Bash Script will not recognize function [duplicate]

I'm trying to create a bash script that will allow you to specify an AWS account that you want to perform some actions in.

I have a variable I need to pass that refers to a file that the script will cycle through.

But the function that performs the actions isn't recognized by the script.

This is the error I get :

./delete_snapshots.sh

What AWS Account:

12345678910

Delete Snapshots in account: AWS Lab

./delete_snapshots.sh: line 14: delete_snapshots: command not found

This is the script :

#!/bin/bash
echo "What AWS Account: ";
read accountnumber
declare -a arr=("12345678910" "109876543212")
for i in "${arr[@]}"
do
  if [ "$i" -eq 12345678910 ]; then
     aws_account="AWS Lab"
     aws_key="lab"
     aws_file="aws_lab_snapshots.txt"
     echo "Delete Snapshots in account: $aws_account"
     delete_snapshots
     break
  elif [ "$i" -eq 109876543212 ]; then
     aws_account="AWS Billing"
     aws_key="bill"
     aws_file="aws_bill_snapshots.txt"
     echo "You are currently in account: $aws_account"
     delete_snapshots
     break
  else
     echo "Unkown account"
  fi
done

delete_snapshots(){
for i in $(cat $aws_file)
do
  echo "*****************************************************************"
  echo "deleting snapshot: $i"
  aws ec2 delete-snapshot --snapshot-id=$i --profile=lab 2>&1 | sed -e 's/^An error occurred.*when calling the DeleteSnapshot operation: //'
  echo "*****************************************************************"
  echo; echo; echo; echo; echo
  sleep 5
  echo "*****************************************************************"
  echo "Verify that snapshot: $i is gone:"
  aws ec2 describe-snapshots --snapshot-ids=$i --profile=lab 2>&1 | sed -e 's/^An error occurred.*when calling the DescribeSnapshots operation: //g'
  echo "*****************************************************************"
  echo; echo; echo; echo; echo
done
}

The script works now thanks for some helpful suggestions. Here's the working form of the script:

#!/bin/bash


delete_snapshots(){
for i in $(cat $aws_file)
do
  echo "*****************************************************************"
  echo "deleting snapshot: $i"
  aws ec2 delete-snapshot --snapshot-id=$i --profile=$aws_key 2>&1 | sed -e 's/^An error occurred.*when calling the DeleteSnapshot operation: //'
  echo "*****************************************************************"
  echo; echo; echo; echo; echo
  sleep 5
  echo "*****************************************************************"
  echo "Verify that snapshot: $i is gone:"
  aws ec2 describe-snapshots --snapshot-ids=$i --profile=$aws_key 2>&1 | sed -e 's/^An error occurred.*when calling the DescribeSnapshots operation: //g'
  echo "*****************************************************************"
  echo; echo; echo; echo; echo
done
}

echo "What AWS Account: ";
read accountnumber
declare -a arr=("123456789101" "109876543212")
for i in "${arr[@]}"
do
  if [ "$i" -eq 123456789101 ]; then
     aws_account="AWS Lab"
     aws_key="lab"
     aws_file="source_files/aws_lab_snapshots.txt"
     echo "Delete Snapshots in account: $aws_account"
     delete_snapshots
     break
  elif [ "$i" -eq 109876543212 ]; then
     aws_account="AWS Billing"
     aws_key="bill"
     aws_file="source_files/aws_bill_snapshots.txt"
     echo "You are currently in account: $aws_account"
     delete_snapshots
     break
  else
     echo "Unkown account"
  fi
done
