Make filled a field mandatory to move a card in a column

[Gregory Wenger]

Hi ! 

Use case : 

I would like my team to be obliged to fill the personalized field "Offer Amount" when they move the card to the "Won" column.

Is it possible ? If yes, how ;)

Txs for your precious help !

Hi Gregory! I don't believe Trello has a feature that will prohibit users from transitioning a card to another status of a field is not populated, however, a workaround could be to create a butler rule that automatically moves the card back into another list when cards are moved to the "Won" list without the custom field populated.

It could look something like this:

Nice Idea! They could put some required field to move to another list. So easy to deploy this.
