How to calculate the value of a custom field based on values selected from two dropdowns?

[Jemima James]

I have two dropdown fields, both of which is a list: 1,2,3,4,5.

Dropdown field names are:

1. Sample impact (1-5)
2. Sample probability (1-5)

What I want is to set the value for the field: Sample Factor (number field) based on changes in value of either of the above fields. Logic for it is: Sample Factor = Sample Impact (1-5) * Sample Probability (1 -5)

How do I achieve this using jira automation smart values?

I have tried the below expressions:

• {{#=}}{{issue.Sample probability (1-5).value}} * {{issue.Sample impact (1-5).value}}{{/}}
• {{#=}}{{issue.fields.Sample probability (1-5).value}} * {{issue.fields.Sample impact (1-5).value}}{{/}}

Sample Factor value gets updated on the issue but automation audit log shows the below error:

• Error rendering smart-values when executing this rule: Failed to get value for issue.Sample probability (1-5).value: {{#=}}{{issue.Sample probability (1-5).value}} * {{issue.Sample impact (1-5).value}}{{/}}

I also tried using custom field id:

• {{#=}}{{issue.fields.customField_idxxx).value}} * {{issue.fields.customField_idxxx.value}}{{/}}

For which i go the error: 

• Failed to get value for issue.fields.Sample_impact_(1-5).value: {{#=}}{{issue.fields.customField_idxxx}} *{{issue.fields.customField_idyyy.value}}{{/}}

Hi Jemima - Welcome to the Atlassian Community!

You shouldn't need the word "value" anywhere in your smart values code. 

So try this: 

• {{#=}}{{issue.Sample probability (1-5)}} * {{issue.Sample impact (1-5)}}{{/}}

Or

• {{#=}}{{issue.customfield_xxxx}} * {{issue.customfield_xxxx}}{{/}}

Thank you so much!

• {{#=}}{{issue.customfield_xxxx}} * {{issue.customfield_xxxx}}{{/}}

This worked for me while the other resulted in the same error as before.
