I am currently working with Crystal Reports Professional 7.0 trying to pull data from an accounting software package. I am trying to calculate the beginning balance for a given month selected by a parameter. I want to calculate it by using the previous month's posted figures. The software stores the figures in the database based off a field called POSTMONTH. I want to be able to take the BEGINNINGBALANCE field (which is 0 for the fiscal year) and add the posted balances for all of the months prior to the one selected in the parameter and use it as a Monthly Beginning Balance year-to-date. From there I want to calculate the monthly posted figures and then add the monthly posted figures to the Monthly Beginning Balance year-to-date to come up with an ending balance year-to-date. I am having problems pulling the figures from the previous months to come up with my Monthly Beginning Balance year to date.
