I am trying to create a calculated Item.

Here is the case, result = (Item1) / (Item2)

when Item1, and Item2 are not equal to zero then I am getting the result, how ever some times my default data can be zero( 0 ), this is case I am getting unsupported exception like Division by zero. Cannot evaluate expression [0.000/0.000000], I am expecting the 0 in this case.

please advise me what i need to do?

is this bug? guide me what I have to do, in the cases where I can get the data both may be zero? so that when I draw the graph it should not break the graph.
