A question about classes [RESOLVED]

[ZoomyX]

I have a class, it looks like this(ill keep it simple):

Public Class Person
     Private m_Name as String

     Public Property Name() As String
          Get
               Name = m_Name
          End Get
          Set(ByVal Value As String)
               m_Name = Value
          End Set
     End Property
End Class

now i create instance of this like so:

     Dim OldMan As New Person

But what i want to do is set his name right away when i create the instance like this:

     Dim OldMan As New Person("Mr. Smith")

What do i have to add to my class to make this possible? I thought i could add a Sub New to my class like this to make it possible but it does not seem to work:

     Sub New(ByVal n as String)
          m_Name = n
     End Sub

but i just get an error saying "Argument not specified for parameter n"

Can someone help me out please, i just need to know how to set a property of a class right when i instance it.
