I seem to be having a problem with initial values for Variables. What I want to do is create a running balance value, so I have a variable with Calc type Sum, Reset type = Report, Increment=none. I have a variable expression such as $F{Amount}. This works correctly, except for one thing. I want to prime the value of the variable, so that it starts off with an "Opening Balance" so to speak. The initialValueExpression doesn't seem to work in the way I would have expected. No matter what I do, the initial value is always zero. Thanks, Milt.
