Assuming this is to happen in the report's detail section, you could use
something like this in the detail section's Print event:
If Not IsNull(Me.RD) Then
Me.txtStreet.Visible = False
Else
Me.txtStreet.Visible = True
End If
Me.RD is the RD field in the record source. txtStreet is the text box
containing the Street. If you hide the text box, the attached label (the
one that shows up automatically when you add a text box) will also be
hidden.
If the default value of RD is a zero-length string you may need to use If
Me.RD = "" Then ... etc., but the first example will probably work.
Note that the Print event occurs before the report is printed, so you will
be able to see the formatting without actually printing the report.
