How can i set the Increase the number in a custom field to start from a certain number

[Robert Jackson]

We have a custom field defined "#" which contains a number which links to old numbering for issues.

After transferring the all 112 issues from our old tracking method into Trello and setting this number for each card manually we tried to create a rule which will set this number to the next highest number when a new card is created.

When we create a new card it always starts the numbering from 1, how can we get it to start from 113?

Huh, this was a finicky issue to get right. Number custom fields don't accept text input. Unless you reference the wildcard system. But you can only reference it if you use the wildcard as part of the Trigger. Starting off with a card that already has a # value nicely sidesteps that, but makes figuring out a good trigger for the Rule a bit difficult, so made it a Card Button instead.

Its technically a Card Button, but it ignores whatever card you're on when you click it to work.

First create a Template card of sorts. Set its # custom field value to 113. And add any default template-y stuff down. Jot down the url of the card (you can see it if you click Share in the card)
Then optionally Archive it, if you don't want people manually messing with the "next #" variable.

Then make the Card button below, replacing both https://trello.com/c/xxxxxxxx links below with the Template url. Of note is that {{%#}} is how you'd access the # value.

Thank you so much for the assistance. That works perfectly for us.
