Hi all,

I was wondering if you could help me in figuring out how I can reference an aggregated field AND sub-aggregated field in my watcher action?  
In this example, I wish to reference `key` and `elasticid` in my watcher action. Right now, I only have `key`

Thank you in advance 🙂

Found the solution - I did not specify my array

`{{second_agg.hits.hits.0.<field>}}`
