I don't know maybe I am doing this wrong but it has worked with other languages I have used. But my problem is that I am trying to nest an array inside of another array for example

array(mixed) arr = ({ 0, 0, 0, ({ 20, 0 }), ({ 20, 0 }) });

Now I am trying to get the first value from the first array using

int num = arr[3][0]

Now I get the error saying

Expected:     int
Got:             array

Maybe I am overly tired? But I know I have used this before.

Dennis
