for each cheklist item and link cards not working

[Carlos Ramírez]

¿why this butto action is not working?

for each checklist item in a checklist named "TAREAS", find a card titled "{checklistitemname}", set the card's description to "|{checklistitemname}|", and link the card with the item

Card is finded, and description is modified, but is not linked with the item

the idea behind is to link Cards with the same name than the checklistitem

Hi Carlos, 

I created the same automation you suggested and I have received this error after I run the automation. Linking card together action can only be used for certain triggers:

To check for errors in your automation, you can go to the command log: https://support.atlassian.com/trello/docs/opening-the-command-log 

It isn't possible to have this automation using card button but you can create a new rule like this and it will work:

when an item is added to checklist "TAREAS", 
find a card titled "{checklistitemname}",  
set the card's description to "|{checklistitemname}|",
and link the cards together

 Hope this helps!
