Can anyone help me with the correct syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query.

I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element… My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class.

The hierarchy I want to create is as follows:

AllBrigades (array of Brigades)  
Brigade (object)  
BrigadeUnits (array within Brigade object)  
Unit (Object to be stored in BrigadeUnits array)

I hope this makes sense!

I have tried various approaches including the following, assuming that I am addressing the first Brigade in the array:

AllBrigades [0] [2].push (MyUnit);

But when I trace this I just get undefined.

Where am I going wrong?
