  (Asked by: username_0 on 2021-02-18)
  
  My aim is to have my vnet and subnet in a seperate resource group from the other parts of my infrastructure i.e Virtual Machines.
  
  I have a short playbook that creates the resource group for my network (vnet & subnet), which works fine. I can build a VM via the portal and all is well.
  
  My other playbook creates a resource group, creates a vmnic and VM. This playbook references the vnet and subnet created in the other resource group.
  
  I'm encountering an error (see below) when referencing the resources in the network resource group I created. I found a [previous post](https://devops.stackexchange.com/questions/3741/can-i-create-an-azure-vm-from-ansible-with-nics-in-different-resource-groups) that has helped by suggesting the use of the "set\_fact" module.
  
  I've tried different ways of entering set\_fact key values (full resource path / part resource path), but I keep getting an error. I suspect it maybe due to interpolation? Note the double "//" in the error message.
  
  Could anyone provide some guidance on where I'm going wrong, please?

  ### Answer by username_0 on 2021-02-19. Score: 1
  
  With a bit trial and error I was able to work out the values for my "vnet\_id" and "snet\_id" variables.
  
  I found using the full ID for the virtual network and not having a "/" before the subnet variable (snet\_id) value fixed my problem.
  
  At the moment I don't fully understand how Ansible/Azure puts it all together, but this has given me enough information to start to understand.
  
  If anyone could point me to some documentation that explains the construction/interpolation of the variables it would be helpful.
  
  ```
    tasks:
     - set_fact:
         vnet_rg_id: "/subscriptions/REVMOVED-SUB-ID/resourceGroups/rg-ansible-test"
         vnet_id: "/subscriptions/REVMOVED-SUB-ID/resourceGroups/rg-ansible-test/providers/Microsoft.Network/virtualNetworks/vnet-ansible-test"
         snet_id: "snet-ansible-test"
  
     - name: Create resource group
       azure_rm_resourcegroup:
         name: "{{ rg }}" # declared earlier in the playbook
         location: "{{ location }}" # declared earlier in the playbook
  
     - name: Create virtual network inteface cards for VM
       azure_rm_networkinterface:
         resource_group: "{{ rg }}" # declared earlier in the playbook
         name: "{{ nic_name }}" # declared earlier in the playbook
         virtual_network: "{{ vnet_id }}"
         subnet: "{{ snet_id }}"
         location: "{{ location }}" # declared earlier in the playbook
  
  ```
