CustomParameterGroups

[hozz__]

I'm having difficulty retrieving parameters associated with a one of my CustomParameterGroups.  I have three custom groups...

1. Material Defaults - InternalName = MaterialDefaults

2. Room Defaults - InternalName = RoomDefaults

3. Room Constants - InternalName = RoomConstants

My Code (below) to retrieve parameters for Room Defaults works fine, but the code to retrieve Material Defaults does not.  I've verified that the groups exist and that there are parameters assigned to every group however no matter what I do, the parameter count for the MaterialDefaults always returns 0.  I can see via the parameters dialog that this simply isn't the case.

Any help would be greatly appreciated.

RoomDefault Code  - Works

    Private Sub GetRDParams()
        Dim allParams As Parameters
        allParams = InvDoc.ComponentDefinition.Parameters
        For i = 1 To allParams.CustomParameterGroups.Count
           If allParams.CustomParameterGroups.Item(i).InternalName = "RoomDefaults" Then
                rdParams = allParams.CustomParameterGroups.Item(i)
            End If

        Next i
    End Sub

MaterialDefault Code - doesn't work

    Private Sub GetMDParams()
        Dim allParams As Parameters
        allParams = InvDoc.ComponentDefinition.Parameters
        MsgBox(allParams.CustomParameterGroups.Count)
        For i = 1 To allParams.CustomParameterGroups.Count
            If allParams.CustomParameterGroups.Item(i).InternalName = "MaterialDefaults" Then
                mdParams = allParams.CustomParameterGroups.Item(i)
            End If
        Next i
    End Sub
