Automation make calculation (beginner)

[Martin]

Hi there,

I'm new to programming. I am doing a lot of automation for my company and now I need to take it to the next level.

I'm trying to figure out how the JSON automation works but some (probably) basic concepts don't reach me.

What I am looking to do here is to take a customer field value, multiply it by a number, then add another custom field value and store it into a field. As simple as that.

usually I get around these kind of issues in my life pretty easilly but this one, I don't seam to find where to start.

I do have the field numbers (or name).

Thanks for your help

Hi @Martin,

I usually use automation for Jira for simple operations like the one you're describing.  

You can follow the "Multiply" example in the documentation below

Please let me know if that helped.

Cheers,

Melo

Hi @Martin 

Yes, and...to what Melo suggests: Please try the way the math operations are described in the documentation.  Some other things to try if that does not work are:

• Check your field types, and if the field is text, you may need to convert with asNumber in order to perform math operations.  For example: {{issue.Story points.asNumber}}
• If your field is in an option list, those are objects and have a value, an ID, etc.  For such field types try to use the value in a math operation.  {{issue.myOptionField.value}}

Kind regards,
Bill

Thank you guys,

I saw the documentation but what I am looking is learning the basics of coding in this. For exemple: why do I have to add the {{ and where to put them... things like that.

I know how to find the custom fields number, I like to dig around. What I need here is just a tip on where to start my learning.

Thanks for replying! I really appreciate your support.

Hi @Martin ,

I was quite new to coding and jira automation too. Personally I started with reeeeaaally easy examples in jira automation, doing some examples from the community (like closing a story when all subtasks are done, transition a story to "in progress" when the first subtask moves to "in progress",...) After some examples, reading quite a lot here in the community and getting deeper into automation I got in contact with smart values (kind of "accidently" :D ). I can´t tell you exactly "why" the {{ }} but reading through and trying out the above mentioned documentation helped me a lot. You´ll get familiar to the format while trying out ;)

Best
Stefan
