Thank you all once more, but
analyzing the situation I came to a simple solution.
I Subtracted the number A - B , A being the first Number
and B the secound number, if A - B = (-) my number is
acending since B will always be grater then A. Else if A - B = (+)
My number is decending since A will allways be grater then B.
A and B varialbles are use for all the Readings ub to 30.

Thank you all for the response
