Hi  
Possibly im not using this correctly.  
Here is the playbook snippet

```auto
        key_name: "{{ aws_key_name }}"
        instance_type: "{{ cms_machine_type }}"
        image: "{{ aws_vm_image }}"
        wait: yes
        exact_count: 1
        count_tag: 
          role:cms
        group_id: "{{ aws_cms_security_group_id }}"
        region: "{{ aws_region }}"
        monitoring: yes
        assign_public_ip: yes
        vpc_subnet_id: "{{ aws_vpc_subnet_id }}"
        instance_tags:
           role: cms
           has_shared: true
      register: 

```

```auto

```

I want only a single instance create with role = cms but the above creates another instance each time its run so am i doing something wrong with this syntax?

Ansible version = 1.9.3 on Trusty Ubuntu

Thanks

```auto

```

```auto

White space issue.

```auto
count_tag:  

```

role: cms

seemed to fix it.
