Well… because I obviously wasn't paying attention when I posted the question and missed the fact that I provided a problem with two solutions.
11 is the answer that I expected with the designated values as posted in Terry's second answer. However, you are right that both answers are valid solutions.
i like puzzles is all, not that i do them anywhere else, but do look forward to your monday madness with anticipation.
so thank you tomk.
forgot to say there's another 2 answer too
