Formatted Naming series #### number stuck

I am trying to apply a custom naming series that is of the formatted kind.

The first time it is used, it works. But the second time it complains of uniqueness. Turns out it keeps on generating the same number for the #### part. How can one get around this problem?

try resetting in Document naming setting.

Put a ( . ) before ######
image

What exactly does this mean?

That does not seem to work.

According to my calculations in v13 that entire functionality is broken.

I cannot even describe it, it just seems to not work at all. Except once. Then somehow it complains about duplicates even though I change the format completely.

Sorry, I misunderstood your question. the format you have given should work fine, make sure ### is inside curly brackets

Ok so yours works.

Thanks!

What version are you on?
