When conditional not working in Ansible

Question

I am using the when conditional in ansible but it doens't seem to work.  If I run the playbook, it never checks with the condition rather it sets the last set_fact value of "shot"

---
- hosts: sandbox
  user: robo
  become: yes
  gather_facts: yes
  tasks:
  - debug: msg="{{ansible_memtotal_mb}}"

  - name: SHOT value for MEM less than 16G
    set_fact:
       shot: 3670016
       when: ansible_memtotal_mb|int <= 16384

  - name: SHOT value for MEM is between 16G and 32G
    set_fact:
       shot: 7340032
       when: ansible_memtotal_mb|int > 16384 and ansible_memtotal_mb|int <= 32768

  - debug: var=shot

Your identation is wrong and when is not an argument for set_fact, it's an argument for a task:

- name: SHOT value for MEM less than 16G
  set_fact:
    shot: 3670016
  when: ansible_memtotal_mb|int <= 16384

- name: SHOT value for MEM is between 16G and 32G
  set_fact:
    shot: 7340032
  when: ansible_memtotal_mb|int > 16384 and ansible_memtotal_mb|int <= 32768
