Re: Formula Question

Just to finish this up, we got lazy and decided to convert them all to dates
and select our range that way.

For the record my boss said he got the formula.

-1(6((-(2(12-x))/|(2(12-x)|)-1)+11) where x is the period. Took him about
4-5 hours to get this figured out. I like the casting to date better.
