Rule with "find" doesn't work

[Frances]

I have two rules set up and I can't seem to get the second one to work. I have two boards - the checklist is on board 1 (Trips) and creates a card on board 2 (Client Tasks). When I check off the checklist on board 1, I want the card that was create to be marked as complete.

RULE 1:

when an item containing "JANE" is added to checklist "Tasks", create a new card with title "{ checklistitemname }" in list "NEW" on board "Client Tasks", link the card with the item, link the cards together, set due date in 2 days, set custom field "Trip" to "{ triggercardname }", add member u/ janesmith to the card, and add the dark pink "Sharon To Action" label to the card

RULE 2:

when an item is checked in a checklist named "Tasks", find a card titled "{ checklistitemname }" on board "Client Tasks", and mark the due date as complete

I've also tried this version: 

when an item is checked in a checklist named "Tasks", find a card titled "{ triggerchecklistitemname }" on board "Client Tasks", and mark the due date as complete

Any ideas why the second "mark due date as complete" automation won't work? (the spaces before/after the { and after the u/ were just to fix the "HTML" to get this to post).

SOLVED! 

RULE 2 needed to be: 

when an item is checked in a checklist named "Tasks", find a card with link "{ checklistitemname }", and mark the due date as complete

(note - take out the spaces after { and before }
