ERROR: Not all code paths return a vale

the error is CalculateScore, BTW I'm a newbie in C#. this is a method from a game I'm working on. MasterMind.

public static long CalculateScore(byte chances, long millisec)
int score;
byte num1 = chances++;
byte num2 = (byte)10;
byte num3 = (byte)10;
switch (Program.currLevelIndex)
case (byte)7:
num2 = (byte)10;
case (byte)11:
num2 = (byte)20;
case (byte)15:
num2 = (byte)40;

if ((int)chances >= 1 && (int)chances <= 3)
num1 = (byte)40;
else if ((int)chances >= 4 && (int)chances <= 6)
num1 = (byte)20;
else if ((int)chances > 7)
num1 = (byte)10;
if (millisec > 480000L)
num3 = (byte)10;
else if (millisec >= 240000L && millisec <= 480000L)
num3 = (byte)20;
else if (millisec < 240000L)
num3 = (byte)40;
score = Convert.ToInt32((int)num2 * (int)num1 * (int)num3);
catch (Exception ex)
score = 0;


Console.SetCursorPosition(Program.x, Program.y);
Console.Write("Your Score was: " + score);
