I'm really new in gis and programming... So could anyone write VBA code for counting average. For example I have 3 columns which are named as JAN, FEB, MART...Each of them have 50 values in column. How can I make new column for counting average of these three columns, and find unique average value of that new column which will be written in message box...

I know how to do it with field calculator, but I have do it with VBA code...
