How can I print something on the first detail line only

[jeep2001]

I have a report that groups detail records by account.
I have a value I would like to print a value on the first detail line of the group. Is there a way to isolate the value for the first detail line of a group in a report.

Thanks

Perhaps something like:

Option Compare Database
Option Explicit
Dim intLineNo

Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
intLineNo = intLineNo + 1
If intLineNo = 1 Then
    Me.txtLineOne = "This is line one"
Else
    Me.txtLineOne = "Blah"

End If
End Sub

Private Sub GroupFooter1_Format(Cancel As Integer, FormatCount As Integer)
intLineNo = 0
End Sub
