Creating running number for my Invoice

[wenzhou748]

I created an event on the Main form's property 'On Load' as below, but on opening the form I got error msg "The expression On Load you entered as the event property setting produced the following error: Invalid outside procedure.
Can you tell me is the problem. I'm using Access 2002.

If IsNull(Me.Invoi ceNo) Then
Me.InvoiceNo = Forms![frmInvoice]![frmIncrement].Form![Increment]
Forms![frmInvoice]![frmIncrement].Form![Increment] = Forms![frmInvoice]![frmIncrement].Form![Increment] + 1

End If


Private Sub Form_Load()

End Sub

Your code has to go in between these 2 lines:

Private Sub Form_Load()

End Sub
