Runtime error 91

[whygh]

When I test my class, I met this problem, "runtime error 91: object variable or within block variable not set"

this is my test code:

Option Explicit
Dim ctest As clsexport


Private Sub Command1_Click()
With ctest
.CName = "name"
.userID = "123456"
.C_export
End With
End Sub


partly code in my class

Public m_userID As String
Public m_CrName As String

Public Property Get userID() As Variant
userID= m_userID
End Property

Public Property Let userID(ByVal vNewValue As Variant)
m_userID = vNewValue
End Property

Public Property Get CName() As Variant
CName = m_Name
End Property

Public Property Let CName(ByVal vNewValue As Variant)
m_CrName = vNewValue
End Property

I don't know how to troubleshot this error.

great appreciated any help!

Are you creating an instance of clsexport anywhere?

Set ctest = New clsexport

open the project in the IDE, go to Tools->Options and in the General tab select "Break on all errors". Run with a full compile (Ctrl+F5) to catch compiler errors before hand. The IDE will stop at the line with the offending error. There you can see which object is not defined.
