I agree that a dynamic time period would be extremely useful. However it
appears that that is not to be. I know that the "LastValue(A+PREV-PREV)"
work around does not work for every situation but sometimes the errors seen
when attempting to use it can still be resolved.
I think I've had an error when the returned value was not an integer, and
the solution was to use Int(). Also, I think a value of zero will usually
give an error, and the solution can be as simple as adding one (+1).
Please feel free to contact me privately if you would like me to explore
other possible solutions for what you want to do.
