Flow sequence lost error in the middle of a palletization

[Jimmy19]

Hi everyone!

I am trying to build this assembly with the KUKA robot in process modeling, where I have a pallet, one cardboard (yellow) on top of it, 7 boxes and a second cardboard on top of the boxes:

I manage to get the pallet, the first cardboard (yellow) and the first box, but when the second box arrives the following error text appears and cannot find why:

If anyone could sujest any solutions it would be much appreciated.

Here is the file i am working on:

As you can see it in the picture, it works
