How to connect Crystal Report 8.5 to VB 6

Hi everyone, Im really new at VB and Crystal Report and i know nothing about Crystal Report 8.5. My problem is, i have this application called CustomerManagement that will keep data in Microsoft Access called 'dbCustomer'
In the form customer ('frmCustomer') i've created a command button 'cmdView' so that the user may view the data in Crystal Report.
My problem is, i've created the link from the form to the CrystalReport1 but this error appear when i click the button 'View' (cmdView) on my frmCustomer:

"This group section cannot be printed becase its condition field is nonexistent or invalid. Format the section to choose another condition field."

Please help me!!! Thank you in advance!

****************************************************************************
on the customer form ("frmCustomer"):

Code:

---

Private Sub cmdView_Click()
Call GenerateCrystalReport
End Sub

---

****************************************************************************
on module 1: (I put this on global)

Code:

---

Public Function GenerateCrystalReport() As Long

Dim recReport As ADODB.Recordset
Dim strSQL As String

''Call connect
Set recReport = New ADODB.Recordset
strSQL = "select * from TableCustomer order by TransactionID, TranDateTime"
recReport.Open strSQL, DBconnection, adOpenDynamic, adLockOptimistic, adCmdText
Set m_crReport = New CrystalReport1

m_crReport.Database.Tables(1).SetDataSource recReport

frmViewReport.Show

GenerateCrystalReport = 1

End Function

---

****************************************************************************
on the frmViewReport:

Code:

---

Private Sub Form_Load()
Screen.MousePointer = vbHourglass
CRViewer1.ReportSource = m_crReport
CRViewer1.ViewReport
Screen.MousePointer = vbDefault

End Sub

Private Sub Form_Resize()
CRViewer1.Top = 0
CRViewer1.Left = 0
CRViewer1.Height = ScaleHeight
CRViewer1.Width = ScaleWidth

End Sub

Its telling you that you are missing one of the referenced fields in your group selection formula perhaps.

Right-click the group section labels at the left of the designer. Select Format Section and then check out any of the buttons that show in Red. There will be a reference to a field that is incorrect in the current report.
