Hi Eric,My guess is that you are passing a name into the FancySSCell constructor that is causing problems. The BasicSSCell class stores each associated data object with a variable name in a visad.formula.FormulaManager, so that you can do things like "A1d1 + A2d1" to add the first data object from cell A1 to the first data object of cell A2, for example. But if your cell name is "A+B" then it will try to name your first data object "A+Bd1" -- an illegal variable name because of the "+" symbol.
I'd stick with letters and numbers for your cell names, just to be safe. If you think your problem is due to something else, then sending a stack trace of the exception you are receiving would be very helpful.

I've build a 4D grid representing samples at

I'm trying to pass this grid to a visad.ss.FancySSCell with a single
addData() method call.
However, the response I'm getting is a visad.formula.FormulaException
with the text:
variable names cannot contain operators
I'm include my field below. Can anyone shed some light?
Thank you,
