Hallo an alle,
Ich sehe den Wald vor lauter Bäume nicht. Bin auch alles andere als gut im Programmieren.
Folgenden Fehler bekomme ich in Zeile 40 .
System.OverflowException: "Die arithmetische Operation hat einen Überlauf verursacht."
Würde mich freuen wen ihr mir weiter helfen könntet. Google habe ich schon gefernt
Danke
