Say I have three columns with different numbers. These numbers may go up
or
they may go down. I want to be able to choose a function and have it find
the
lowest number out of the three colums.

Column 1 Column 2 Column 3
215 185 398

I want the function to choose the middle because it is the lowest.
But next week the lowest might be in column 3.
