Update story point as the sum of story points of linked issues

Question

I need to update the story point of an "Initiative" as the sum of the "linked" epics. So epics are linked to the initiative (not as a subtask but as a link). Whenever the story point of the epics change, the change should get reflected in the way that the sum of story points of all the linked epics should be = story point of the initiative

1.  When: the value of story points changes

2. If the issue type is epic and there are linked issues

3. For the linked issues (which means the for initiative}

Story point  = {{issue.issuelinks.Story Points.sum}}

However, this is not working. The story point for the initiative is zero even when the story point for epic has values

This is similar to what was done here

Please help, urgent!

If you are adding points between linked issues, you could also do it through the explanation found here: You can find the full details here as well: https://community.atlassian.com/t5/Automation-articles/Jira-Automation-Sum-Up-Story-Points-from-Epics-e-g-Initiative-gt/ba-p/1926311

We managed to get a sum of story points with the attached structure:

But here are the details:
WHEN: Field Value Changed to STORY POINTS

IF: Issuetype does not equal: EPIC

BRANCH: For Epic (Parent)

ACTION: lookup issues and include a JQL: "Epic Link" = {{issue.key}}
ACTION: EDIT ISSUE FIELD: Story points

Value: {{lookupIssues.Story Points.sum}}

This was the way we managed to sum up Story Points.
