nested

I'm trying to build a nested array: First, I make a "PlayerItems" array which will contain 10 arrays, each containing item objects, corresponding to the inventories of each player in the game. On the indicated line, I get the following error: error: void valued not ignored as it ought to be What is the void value here? If I used [[PlayerItems objectAtIndex:i] addObject:myitem] instead, the program compiles but crashes. If I comment that line out, it compiles and runs OK.
