[AccessD] Conditional Display of TextBox in Report Detail

Greetings:

Using Access XP. I calculated field in the detail section of a report
that compares an invoice amount with a check amount. I'd like the
textbox to display if the value of the textbox does not equal zero. I've
tried to use the following code in the "OnFormat" property of the detail
section:

Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
On Error GoTo ERR_OnFormat

    If Me.Difference = 0 Then
        Me.Difference.Visible = False
    End If

Exit_ERR_OnFormat:
    Exit Sub
    
ERR_OnFormat:
    MsgBox Err.Description
    Resume Exit_ERR_OnFormat

End Sub

This code correctly detects the first textbox where the value <>0, but
doesn't find any others (I've checked, and I should have a couple of
other textboxes displaying).

Thanks in advance for your help.
