ADODB error handling variable not setting - vba

Question

I building an ADODB error trap but for some reason, by errSQL.Number and errSQL.Description both give me a "Object variable or With Block variable not set." error....here is my code so far...I have the active x object enabled and I thought that .number and .description are correct...any help would be awesome! The query I'm running also purposely will send an error.
When I comment the error trap out, I do get a message box with a SQL syntax error but can't seem to trap it like below...
Public errSQL As ADODB.Error
Public strErrODBC As String
Private Sub verifySQL()
Dim strSQL2 As String
Dim cn As New ADODB.Connection
Dim cdTxt As String
Dim rs As New ADODB.Recordset
Dim intVerify As Integer
On Error GoTo ODBCErrorHandler
cn.ConnectionString = "DSN=source;"
cn.Open
If cn.State = adStateOpen Then
rs.Open "SELECT CASE WHEN MAX((CASE WHEN " & Forms!dlgSplitName.lstbxFlds.Column(0) & " " & cdTxt & " THEN 1 ELSE 0 END)) =1 THEN 1 ELSE 0 END FROM table;", cn
Else
End If
intVerify = rs.Fields(0).Value
If intVerify = 1 Then
insrt_Test
ElseIf intVerify = 0 Then
MsgBox "No records were found with the code text logic.", vbExclamation + vbOKOnly, "Spliy by Notification"
End If
ODBCErrorHandler:
Debug.Print errSQL.Number
Debug.Print errSQL.Description
strErrODBC = "A SQL error was encountered with the code text logic." & vbCrLf
strErrODBC = strErrODBC & "Error " & errSQL.Number & vbCrLf
strErrODBC = strErrODBC & " " & errSQL.Description
MsgBox strErrODBC & vbCrLf & "Please try again.", vbCritical, "Split by field code text error."
cn.Close
End Sub

The problem is that the errSQL ADODB Error object is never set to anything. the Connection object has an error collection that you need to use to display the errors. Try this:
ODBCErrorHandler:
Dim ErrorCount As Double
Dim strError As String
ErrorCount = cn.Errors.Count
strErrODBC = "A SQL error was encountered with the code text logic." & vbCrLf
If ErrorCount > 0 Then
For index = 0 To (ErrorCount - 1)
Set errSQL = cn.Errors.Item(index)
strErrODBC = strErrODBC & "Error " & errSQL.Number & vbCrLf
strErrODBC = strErrODBC & " " & errSQL.Description & vbCrLf
Next index
End If
MsgBox strErrODBC & vbCrLf & "Please try again.", vbCritical, "Split by field code text error."
cn.Close
Hope this helps.
