Use case:
I have bug cards that are manually being linked to task cards as "caused by".
(This would be the trigger)
The task cards are linked to story cards as "testing preparation for".
Using automation I want the bug card to link to the story card also as "caused by".

My thought was I could link to the task, and using the 'testing preparation for' link, find the story card and then link it to the bug (trigger) as a causes/caused by link. but I keep getting the causes/caused by link on the task, it is driving me batty....
Below is the Automation I've tried....

A pre-emptive thanks for assisting.
