Re: Result changing


Hi Jacopo,
hard to tell without an example. Looks like you are setting a variable 
that did not have a value (or a different value) the first time. What do 
you mean by: "canceling the result". Are you aborting a calculation. If 
yes, it may possible that a variable will have a different value than if 
the calculation proceeded.
