VBA Custom Attribute Editor

I am trying to create a custom attribute editor by using fixo and metal_pro's code as a base but I'm getting runtime error '424' object required. The de****** is pointing out line AttList = oBlkRef.GetAttributes but I can't figure out what's wrong. I know the basic's of VBA but i'm new to it, so any help would be appreciated.

Option Explicit
Dim oBlkRef As AcadBlockReference
Sub Change_it()
   Dim inspt As Variant
   Dim oEnt As AcadEntity
   Dim i
   ParentSymbolForm.Hide
   ThisDrawing.Utility.GetEntity oEnt, inspt, "Select object:"
   ' Checks if you selected a block.
   If TypeOf oEnt Is AcadBlockReference Then
       Set oBlkRef = oEnt
       ' Check for attributes.
       If oBlkRef.HasAttributes Then
           Dim AttList As Variant
           ' Build a list of attributes for the current block.
           AttList = oBlkRef.GetAttributes
           ' Cycle throught the list of attributes.
           For i = LBound(AttList) To UBound(AttList)
               ' Check for the correct attribute tag.
               If AttList(i).TagString = "TAG1" Then
                   ParentSymbolForm.ComponetTag.Text = AttList(i).TextString
               End If
               If AttList(i).TagString = "DESC1" Then
                   ParentSymbolForm.TextBoxDesc1.Text = AttList(i).TextString
               End If
               If AttList(i).TagString = "DESC2" Then
                   ParentSymbolForm.TextBoxDesc2.Text = AttList(i).TextString
               End If
               If AttList(i).TagString = "TERM01" Then
                   ParentSymbolForm.TextBoxPin1.Text = AttList(i).TextString
               End If
               If AttList(i).TagString = "POS1" Then
                   ParentSymbolForm.TextBoxSwPos1.Text = AttList(i).TextString
               End If
           Next
       End If

       ParentSymbolForm.Show

   Else
       MsgBox "You did not select a block."
   End If
End Sub

Private Sub SelectButton_Click()
   Call Change_it
End Sub

Private Sub ChangeButton_Click()
   Me.Hide
   Dim AttList As Variant
   Dim i
   ' Change attributes for the selected block.
   AttList = oBlkRef.GetAttributes
   ' Cycle throught the list of attributes.
   For i = LBound(AttList) To UBound(AttList)
       ' Check for the correct attribute tag.
       Select Case AttList(i).TagString
       Case "TAG1"
           AttList(i).TextString = ParentSymbolForm.ComponetTag.Text
       Case "DESC1"
           AttList(i).TextString = ParentSymbolForm.TextBoxDesc1.Text
       Case "DESC2"
           AttList(i).TextString = ParentSymbolForm.TextBoxDesc2.Text
       Case "TERM01"
           AttList(i).TextString = ParentSymbolForm.TextBoxPin1.Text
       Case "POS1"
           AttList(i).TextString = ParentSymbolForm.TextBoxSwPos1.Text
       End Select
   Next

End Sub

Not sure but oBlkRef.HasAttributes maybe oBlkRef.Attributes search here under BIGAL for some block attribute code should give correct wording.

Found this aAttributes = blk.GetAttributes if true block has attributes. Look at your code your doing this but need to move up to IF

If oBlkRef.HasAttributes Then change this line
.
.

' Build a list of attributes for the current block.
Dim AttList As Variant
If AttList = oBlkRef.GetAttributes Then
.
.

I will look into that. Thank you
