@yankeeinlondon no worries. All part of learning. You won’t be able to use it in that part of the `serverless.yml`.

See this example

```auto
service: foo
provider: # Not CloudFormation
  name: aws
  iamRoleStatements: # You can use CloudFormation here
    ...

functions: # Not CloudFormation
 ....
resources:
  Resources: # This section is CloudFormation
    SomeResource:
       Type: AWS::IAM::Role
       ...
           # something like this to build an ARN
           Resource:
             Fn::Sub: 'aws:ec2:${AWS::Region}:${AWS::AccountId}:xxxxx:xxx/*'

```

If you’re just using the AccountId from IAM you should be able to use it directly rather than through a custom property.

Hope that makes sense. P.S. it’s off the top of my head so there might be syntax issue but should be close 🙂
