You still aren't giving us any useful information to help you. Like the code you wrote for the 'partial product addition+accumulation', which is where you have a problem. Are we supposed to read your mind and see where you made a mistake? If you don't have code then you could show us how you compute the output maybe someone will spot a mistake in your calculation.
Actually, I don't expect you to actually supply any information as that seems to be a trend in your posts (I reviewed all 41 of them). Even the ones where you supply an "answer" can be relegated to the useless information pile.
