How Can I automate original estimate from child to parent in jira cloud

I am using Jira Cloud (Lite) and I am less familiar with this edition of Jira, I have only used Standard in the past. 

I would like to have the Original Estimates on my subtasks, update to their parent (Story).

I have managed to get the automation, to do something but the number is not right. 

I have two test subtasks with 2d and 1d logged, and the parent now shows 36w with this automation running. I can't seem to get it to role the Original Estimates up from the subtasks correctly. It either doesn't work or does it wrong.

This is what's in the last box:    {{issue.subtasks.Original Estimate.sum}}

Is it taking original estimates from all my projects subtask and not just the ones attached to the parent?

Any assistance would be appreciate, I have looked on line and tried a number of different things, without luck.

Thanks

Hi @Sarah Jones , 

I think you will find the post from @John Funk "How can I sum up multiple issues into a parent number field" useful: https://community.atlassian.com/forums/Jira-articles/How-Can-I-Sum-Up-Multiple-Issues-into-a-Parent-Number-Field/ba-p/2882712 

It also helped this other community member with a use-case that seems very similar: https://community.atlassian.com/forums/Automation-questions/Sum-up-Original-estimated-hours-from-child-tasks-to-parent-Story/qaq-p/3105458 

Hope that helps. Have a nice day! 

Rik

@Rik de Valk Sadly this has not helped everything seems to be right from what I can find and see but it just does not add up correctly.

Hi @Sarah Jones 

Welcome to the community.

After your Branch statement, delete existing Edit issue step, and below:

Add Component -> Then: Add an action -> Select "Lookup Issues"-> Give JQL => "Parent" = {{yriggerIssue.key}}
Then Add Component -> Then: Add an action -> Select "Log Action"-> Enter => {{lookupIssues.original estimate.sum}}
Finally, Edit Issue -> Choose "Original Estimnate" and give below as value:
{{#=}}{{lookupIssues.original estimate.sum}}{{/}}
