Conditional Formatting by Row Across Multiple Measures

Hello,

First, thank you so much for the hard work helping me.  The only issue i'm having is that each individual Month is in fact it's own unique measure (please see screen shot).  The reason for this is because i'm appending a data file with YTD revenue information and appending onto the previous one.  In this case, I have subtract each previous month in order to get the revenue earned "for that particular month" - not YTD.  So, since each month is it's own unique measure....in your example, i cannot use one particular field (Sum of Sales) to capture all months.  Is there a way to use the MINX and MAXX features in your formula, but list out each unique month measure?  Please let me know if this makes sense.
