I read the combination macro wrote previously, but I don't know if it will
work for my situation... I have number 1 to 10 from Monday to Sunday. But
each number can become another new set of numbers the next day. Like I have
#1 on Monday, on Tuesday, I can have #2 or #1(a), which got out from #1.
Then, when Wednesday comes, I can pick #3, #2, #2(a), or #1(b). It's
combination within combination situation, can someone help me out on this??

Thanks a million!
