Hi,

I feel like I’m stuck at a very simple problem but cannot move forward untill this one is solved and therefore I need a little help.

I have one list of elements grouped/chopped in two ways:

With these two lists I try to reconstruct the ‘desired output’.

What the final list is telling me is that i have 6 elements in a project, 3 elements on the first floorlevel and 3 elements on the 2nd floor. On the first floor there is a group of 1 and a group of 2 elements, on the second floor the same but in another order.

Any ideas how to do this?
