I want to synch a card between 3 boards, but how!?

[Bas van der Star]

Hello,

I have tried a lot with the automatisations but it won't work. I have a list with repairs. And at 3 boards we have to see it. And if i put a comment at the other board it has to synch but also on the 3rd board. What is the right way to automatic it. 

Because i link the card together. And i put the action that you have to look at the first card that is linked and the last card. And i used {commenttext}. So if someone put a comment you will see it at the other cards. Sometimes i see the  comment a couple of times at the other board. I looks like a loop. And at the other board i don't see any comment.

Can you tell me the right way to install this?

You could use the card syncing powerup like Unito https://trello.com/power-ups/5c75708a72eecc4565ecacf5
