Variable 'Random Number' is used before it has been assigned a value.

[neothod]

Variable 'RandomNumber' is used before it has been assigned a value. A new reference exception could result at runtime.

Code:

    Sub RandomizeConLandLaunch(ByRef con As Integer)
        Dim RandomNumber(,) As Integer
        ConLandLaunch(con) = RandomNumber(1, 30000)
    End Sub

what should i do ?
