Hi Brad, If I remember correctly from my Linear Algebra classes, in order to multiply two arrays, their dimensions have to be such that the first dimension of the second array equals the second dimension of the first array, so they should be of the sort: Array1 [m x n] and Array2 [n x p] which means that, in this case, as it's not a square array, it can't multiply it with itself. Try again wih a square array.
Hope this helped, Jan Schenkel. "As we grow older, we grow both wiser and more foolish at the same time."
