How to ensure a rule triggers exactly once on a card no matter where that card is on the board?

Hi.

I'm trying to set-up a rule so that whenever a new card is added to a list, a checklist is automatically created for that card. It worked great. Problem is, however, when I accidently moved that card into a different list, then back to its home list, the rule triggered again and created a duplicate checklist on the same card. What am I doing wrong? Is there a foolproof to prevent something like this from happening, or is it a loophole? 

Thanks

Hi @Leena Abu Shmais First question, what rule are you using to create the checklist.  If you use the rule, "add the checklist named [checklistname] to the card", it wont duplicate the checklist if the card gets moved back.

You could also do something like adding a transparent label (call it "runonce" for example). Then...

Make your rules

1

When a card without label "runonce" is added to list [listname], add the checklist [checklistname].

2

when a card is move out of list [listname], add the label "runonce" to the card
