Renumber Sheets Biomorph

[Tim]

For some reason when Renumbering sheets from schedule using Biomorph nodes returns Empty List

[Alien]

Maybe show what’s coming out of each node?

Hi Have tried with an empty string and not empty list ???

and lets say you already have a number in use you could give a temp name…

Thanks @sovitek your solution worked just fine. Curious to know why the original failed.
