Getting stuck here.

In class called cNum I have this:

Option Explicit

Private m_rP As Double
Private m_iP As Double

Public Property Get rP() As Variant
rP = m_rP
End Property

Public Property Let rP(ByVal rPart As Variant)
rP = m_rPart
End Property

Public Property Get iP() As Variant
iP = m_iP
End Property

Public Property Let iP(ByVal iPart As Variant)
iP = m_iPart
End Property

In a module I have this:

Sub test()
Dim cNum1 As cNum
cNum1 = Set_cNum(11, 3)
End Sub

Function Set_cNum(rPart As Double, iPart As Double) As cNum
Set_cNum.rP = rPart
Set_cNum.iP = iPart
End Function


But I dont know where´s the flaw.
