I am trying to sort my schedule by a **Sorting** parameter and **Sheet Number**. Once my sheets are sorted, I want to apply a sequence from 001 to however many sheets I have using a parameter called **Sheet Counting**. I was trying to use List.GroupByKeys, but I got stuck for a few hours. My Sheet **Counting values** are all over the place ☹

Could someone please help a little?

Thank you in advance!

Hi @Koco and welcome, did you try the node `List.SortBykey` instead of `List.GroupBykey`?
