Hello, I was able to get my problem by following your advise. everything works if i start beginning of the year but if i start in the middle of the year it does not. so this is what it looks like.
Months/Year Opening Months Activity New Column(I called it a difference column)
03/2014 $200 $200
04/2014 $100 $300
05/2014 $20 $320
06/2014 $10 $330
07/2014 $30 $360
which is fine but if i start my report from 06/2014 it will pick up $10 and not $330 where as i want it to pick up $330.
is there a way to do that please?
Thanks.
