How can I use automation to set a custom field value to be the product of other custom fields?


I'm having a lot of trouble setting up what I thought would be a simple and straightforward automation.

I have 3 number format custom fields: Impact, Urgency and Priority Score. My goal is to set the value of Priority Score to be the product of Impact * Urgency.

I've tried all sorts of variations of formulas from these forums but not having luck. For some reason, the automation rule is interpreting the value of Impact to be null, so if I change the multiplier to an addition sign, I get the result of the Urgency value (5) as the value of the Priority Score, however if I change it back to the multiplier I get an error in the logs.

Any help would be seriously appreciated!

Hi @Tucker Bentley 

Welcome to the Community!!

I created three separate fields to edit a new priority field and with the same formula, it's working!


Check for the field name without whitespaces, make sure your field name has no extra spaces, and if so create the separate field and the check.


Thanks for your reply; I've tried this, and I've tried deleting and re-creating the "Impact" field several times...

Oddly, when I create a new field (for testing purposes) called "Impact_2" and plugged that into the worked.

I think when I'm entering "issue.Impact" in the formula, Jira is using the original, very first custom field labeled "Impact" that I created -- which is deleted and therefore null now.

Is there a way I can see the custom field IDs instead, and use those in the formula rather than the custom field name to avoid pointing to the wrong (deleted) "Impact" field?

Thanks again!

I was going to suggest it sounded like you might have a second field "Impact" on the system that Automation is picking up instead - so good catch!

We do support using the custom field id directly: {{issue.customfield_12345}}. It sounds like that might be the best approach in your case.

Also, another trick that may be useful when performing math functions is that you can set a default value in case one of the fields is empty.  e.g. {{issue.Impact|0}}*{{issue.Urgency|0}}.   This will just stop your rule from erroring out unecessarily.

Thanks for your response Brydie!

How can I see the "custom field IDs" for each custom field? I'm not using the API (not an engineer) so I can't easily access those endpoints, unless there's an easier way to go that route. It sounds like these custom IDs will solve my problem, though. I'm also not an Admin on our org's Atlassian account, though I am an admin on my specific Jira board.

Will my original, first custom field labeled "Impact" ever be deleted, or will it always be reference-able via that name? How can I reference subsequent "Impact" fields; is there a convention whereby I can try Impact.1, impact.2, etc. until I recognize the "current" field's value?

edit: I was able to get a look at the custom fields view in admin settings, and my new custom fields aren't showing up I can't view their custom IDs.

For reference, this is a team managed ("next gen"?) project.

Thanks again
