As JB has stated previously he can't review files in the new XL2007 format so if you want him to review post as .xls
Regards you problem - using the formula with ranges as you have it would require array entry (ie confirmation with CTRL + SHIFT + ENTER not just enter)
You will find that once confirmed as an Array the formula applied to your matrix generates identical results to that of the version using the inline array (sum of green = 12864)
If you want to avoid the Array entry you can encase the necessary elements within outer INDEX calls, eg:
however, this would be less efficient than the Array given the additional function overhead - whether or not you would notice the difference is debatable (I suspect not).
I've not reviewed the formula itself obviously.
