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.
