Anyone know what I am doing wrong here? I am trying to get a rolling 12 month sum, but seems to be just taking the previous months total and adding 12 to it?!?
I thought the 0,12 section was telling it to go 12 months back and include the current month. (IE 11-2012 to 10-2011)
What am I doing wrong? I can not use the accumulate 12 steps back because I need to use this expression in another expression and also uses a rangeavg.
