Hello
The Arithmetic.gvi is working good for me
The Calculator.gvi is missed dependencies and event structure events. You need to reconfigure it, because when you convert VI to GVI most of all, you need reconfigure all dependencies, but the logic of your VI is converting without any issues.
The main reason of missed dependency is unwired cluster which is responsable for events in event structure. Also, as I can understand, the cluster is missed dependency from Arithmetic GVI.
