OK, I have a promotion begin date, and a promotion end date in 2 columns. I also have, say 50 columns with weekly sales data and a date heading. What I need to do is to average this data in 3 different areas. Avg before promo, during promo, and after promo. I also need it to average data that does not have a zero, which I believe I know how to do(=AVERAGE(IF(A2:A7<>0, A2:A7,""). Right now I'm manually averaging this data based on the different beg. and end dates, but it's a very manual process as the beg. and end dates very from title to title. Any ideas?
 

Excel Facts

VLOOKUP to Left?
Use =VLOOKUP(A2,CHOOSE({1,2},$Z$1:$Z$99,$Y$1:$Y$99),2,False) to lookup Y values to left of Z values.

Can't you use a similar Average(if formula and make the criteria <= cell with reference begin date, etc..?
