Need help for calculation

Question

Hi team,

I need help to create a subtraction of values (numbers) in my automation. I have 3 custom fields name as below :

1. Result

2. Duration A

3. Duration B

All 3 of these custom fields are number types set in custom field as well.

I need help to make the subtraction of A from B then the outcome should be Result.

B-A = Result.

I have tried with

{{issue.customfield_B}} - {{issue.customfield_A}}

but both did not work and I cant find out why because the result does not appear and in audit log it appears as success :(

I was asking to see your complete automation rule, for context.  Not just the smart value expression you are trying.

It is possible the result is null or empty because of the way the expression is used.  Seeing the entire rule and audit log details will help to clarify that.

When posting the audit log details, please show the entire image for the details of the rule execution.  That will show which steps did, or did not, execute.

Hi @nasiruddin.nordin

In this instance - A, B, and Result are all number fields. Is this the same in your scenario?

thats what I did but there's no result that came out. It states success in the audit log.

For the result, what is the data type that can come out with the result? numbers? Strings?
