Custom math equation in a custom numeric field

[Deleted user]

I've added a custom numeric field to my issue type and I want the number displayed to be based on 2 other custom field entries. For example it will be pulling the values from field A and B to do: (A +B) /2

I saw some examples like below in the docs but I can't enter anything but numbers in that field. Am I missing something?

{{issue.My Number field}} + 43

Hi @[deleted] 

Usually, you'd use Automation to manage this - for example...

• Trigger: Field A updated
• Condition: Field A and B are both populated
• Action: Edit Field C - set value based on a smart value math calculation

See these help documents for more information.

If you need more assistance with the specifics of the rule - please let us know the fields, and what the calculation would be!

I don't have access to automation so I thought there's a more basic way to just use a custom expression directly in the custom field

Hi @[deleted] 

If you're on Jira Cloud, Automation is a native feature - it comes in two levels...

• Project Admins can set automation rules for their own Project
• Jira Admins can set multi-project and global automation rules

Unless your Jira Admins have turned off project-level rule creation, then only Jira Admins can create all rules.

Are you a Jira Admin? If not - could you check with them to see if they would create a rule for you, or give you access to create them?

Oh, I understood it to be a Premium feature but maybe I misunderstood. I'll have another look at Automation. Thanks

Hi @[deleted] 

Automation is available for all levels of Jira plan, including free. There are just some variances between the plans (such as execution limits, etc).

Let us know how you get on with your rule!

Hi @[deleted]

Have you tried pasting the smart value formulas.

Can you also share your rule details?

the numeric field only takes numbers so I can't even input smart value formulas, as I understand it. But maybe I'm missing something obvious

You need automation. If you don't have it you will need other 3rd party plugins.
