Running sum based on Calculation
Hiya, fellas
I've a report like this: REPORT HEADER+++++++++++++++++++++++++++ TripJob TravelDaysTotal (=Sum([TravelDays])) PAGE HEADER+++++++++++++++++++++++++++++ TRIPJOB HEADER+++++++++++++++++++++++++++ ~labels~ DETAIL++++++++++++++++++++++++++++++++++ ... StartDate EndDate TravelDays (=DateDiff("d",[StartDate],[EndDate])) ... TRIPJOB FOOTER+++++++++++++++++++++++++++ PAGE FOOTER+++++++++++++++++++++++++++++ REPORT FOOTER+++++++++++++++++++++++++++ simple enough, right? The report is opened based on the user's selection of [TripJob] from a form. When I open the report the system struggles and asks for a param value for TravelDays. Of course, the end user is not providing this data, it is calculated by the report. Clearly I've got some timing issues he how can [TravelDaysTotal] calculate [TravelDays] without the form being fully loaded, right? Thanks in advance! /amelia

Of course, you can't calculate controls...
so i'm using this: [TravelDaysTotal] =SUM(DateDiff("d",[StartDate],[EndDate])) works just fine. :: sigh :: /amelia "aaearhart" wrote: Hiya, fellas I've a report like this: REPORT HEADER+++++++++++++++++++++++++++ TripJob TravelDaysTotal (=Sum([TravelDays])) PAGE HEADER+++++++++++++++++++++++++++++ TRIPJOB HEADER+++++++++++++++++++++++++++ ~labels~ DETAIL++++++++++++++++++++++++++++++++++ ...
