Generate random numbers with fixed sum and different constraints

Hi. I followed the previous thread http://www.mathworks.com/matlabcentral/newsreader/view_thread/324503

But there is an error message if lo = [1 0 2 1 0] up = [5 6 4 4 2] and s = any number between 2 and 6.

2 and 6 is the max number whose both lower bounds are 0.

Can anybody help me to fix this problem?

Thanks.
