Replace multiple empty list entrys with other lists

Hey, i have 2 exactly reversed lists that im trying to combine, the first lists empty lists would be the seconds list filled out lists and the other way around. Im trying to fill the empty lists with the correct lists, but all im getting is only the first entry of the list not actualy the list itself… any advice? Should be fairly simple but im struggling :smiley:

List.AddItemToEnd with correct lacing, followed by a List.Clean should do the trick.

thanks will try that out later today!
