>Can't seem to get this one to work. I created 2 variables julTotal and julPrior for July. julTotal sums jul and prints OK in the group footer. julPrior is initialized at 0 and is not reset. Tried _vfp.SetVar('julPrior',julTotal) in all the onentry and onexit values but all I ever get for its value is 0 or the total for the current detail band.

Let's try to create julPrior not as a variable in the report, but as a local (or private) variable in the calling program. Or you may try to create this variable as public in report's DE Init method and release it in its Destroy. I think it should work this way instead of using report variable.

Also note, that I'm trying this theoretically, without VFP close by.
