Calculate Value for custom field from other custom fields

[Dani Miles]

I have 4 single select list custom fields all with the same values which are alphanumeric:

• 0 (No impact)
• 1 (Negligible)
• 2 (Minor)
• 3 (Indirect)
• 4 (Moderate)
• 5 (Major)

I want to calculate a new numeric field from these values, I was hoping to do something like below but it is not working. I am not sure if the main problem is being the alphanumeric field values I am trying to pull as I can't even seem to pull one custom field value into my new field. 

{{#=}}{{issue.customfield.asNumber}} + {{issue.customfield.asNumber}} +{{issue.customfield.asNumber}} +{{issue.customfield.asNumber}} + {{/}}

I am not interested in any add-on's just want to know if I can do this with smart values.

Hi @Dani Miles 

As your single-select values contain a number and text, you could extract the number before the operations, such as using the left() function: https://support.atlassian.com/cloud-automation/docs/jira-smart-values-text-fields/#left-int-length-

For example:

{{issue.customfieldA.value.left(1).asNumber|0}}

I added a default of 0 to the end of the expression.

Kind regards,
Bill

Thanks Bill, this worked perfectly. I had tried {{issue.summary.charAt(1)}} which hadn't worked but this worked perfectly.

Hi @Dani Miles , 

the alphanumeric value might be the issue. Try with just number field and it should work. 

Sum of smart values 

{{#=}}{{issue.customfield1}}+{{issue.fcustomfield2}}+...{{/}}

Thanks Najm, 

You were right it didn't like the alpha characters I just needed a way to strip them.
