Hi Folks ..

I need to be able to select  the last 3 in a series of cells that change on a weekly

so i week 1 there would be 1 cell  no action 
week 2                              2 cells  no action 
week 3                               3 cell sum three cells 
week 4                               4 cells sum last three
week 5                               5 cells sum last three  

and so it goes on for 8 weeks always just summing the last 3 cells in the
series  then divide by 3 subtract 30 = result ..

That is rather vague. Where is the week number? How is the series represented? What do you want to 
do with the result?
