I made a scripted field in Kibana using the below which syntactically is fine but doesn't function properly.  
I want to take the amount of documents with "Execution", divide that hit count by 10, then multiply that number by 100 to get a percent.

```auto
if (doc.containsKey('Execution') ) {
    return Integer.parseInt(doc['tactic.keyword'].sum / 10 * 100)
}

```

When using scripted fields from kibana, the scripts only have access to document level data.
