As there are some notes with alternative positions, I want to create a table where each row has a possible combination of positions. In column 0 there will be the total slide length per row, so I can find the combination with the smallest total slide length.</div><div>If there is an alternative position possible for a note, it creates new rows and copies the previous values. But for some reason, when I try to copy a cell in the next for-loop, that value is always nil, although it was filled in the previous loop...</div><div> </div><div>I am a total newbie to Lua and to some degree to programming in general, so I might not be doing this the most elegant way, but if I insert some print lines, the program does everything I want.
