Perhaps I wasn't entirely clear. The problem isn't only keeping the
output within the desired range (although that is a problem which your
solution should help). The main problem we are having is near the edges
(0 and 100). Since the input variables are the same at the edges, the
output is equally in the states of 0 and 100. When the two are combined,
the net output becomes 50 instead of the desired 0 or 100. Perhaps there
is a better way of combining the outputs so that only one of the states
is chosen if it is in one of the edge cases.

Thanks for any help.
