Count how many people commented on ticket

[tasha tokunova]

I want to calculate how many people commented on the ticket via the automation rule. 

I assume you need to create a new field, set the default 0 value, and then somehow add +1 on every new person who commented on the ticket. 

Does anyone try to implement something like that?

Hi @tasha tokunova ,

I think it is possible with a number custom field and a automation rule.

On https://support.atlassian.com/cloud-automation/docs/what-are-smart-values/

and
https://support.atlassian.com/cloud-automation/docs/jira-smart-values-math-expressions/

I see that you can use math-functions.

I think something like
{{#=}}{{issue.CustomField}} + 1{{/}}

Regards,
Marco

Unfortunately, the trick is it's not a CustomField. There should be some logic to extract the email of who commented on the ticket.
