JMWE error "expected a number but got" on a sum() event-based calculation.

[Sally Wheeler]

I am new to using JMWE and I probably have the syntax incorrect but I cannot figure out what is wrong.

I have an issue type named shipment in which a number field is entered with the number of samples in that shipment.

This issue type is under an epic.

I would like a total number of samples field to be shown on the epic view screen where it is continually updated every time the number of samples field is updated in any shipment for the epic.

This is what I did. But the field still says None. I even went to a shipment and switched a number and switched it back to hopefully trigger the calculation and still nothing. Can you help to clarify what I am misunderstanding? The error it states: "expected a number but got: | sum({issue.fields.customfield_10083})"

Depends on the project type, and version of JIRA Agile/Software.  In the JIRA I'm looking at though:

Scrum and Kanban:

•  Bug
•  Task
•  Sub-task
•  Story
•  Epic

Simple development:

•  Bug
•  Task
•  Sub-task
•  Improvement
•  New Feature
•  Epic

Remember these are just defaults by project type.  There's no harm in changing them to what you need.

Thanks - I just couldn't believe this isn't documented anywhere !
