Resetting a Sum or Count based on a Condtion

[jgoddard]

I'm trying to figure out a problem I'm having in a Jasper Ireport and can't seem to get it.  I have an integer variable that I want to increment by 1 if a certain condition is met.  The condition is:

$V{Current Result} > $V{Last Result} ? 1

and if the condition isn't met, I want it to reset to zero.

I realize that there is a sum function that you can set that resets on a group change, but I don't want it to reset on the group, only if the above condition isn't met- hope this makes sense.  Thanks in advance.
