I am using the following to get information from Sheet1 to Sheet2.

Sub Getdata()
msg = "Do you want to filter the data now?"
Style = vbYesNo + vbDefaultButton1 + vbQuestion
Title = "Filter"
response = MsgBox(msg, Style, Title)
If response = vbYes Then
Application.ScreenUpdating = False
With Worksheets("Sheet2")
Set rng = .Range(.Cells(2, 1), .Cells(Rows.Count, 1).End(xlUp))
End With
With Worksheets("Sheet1")
Set rng1 = .Range(.Cells(2, 3), .Cells(Rows.Count, 3).End(xlUp))
End With
For Each cell In rng
cell.Offset(0, 2).Value = Application.VLookup(cell.Value, rng1.Resize(, 10),
7, 0)
cell.Offset(0, 3).Value = Application.VLookup(cell.Value, rng1.Resize(, 10),
8, 0)
cell.Offset(0, 4).Value = Application.VLookup(cell.Value, rng1.Resize(, 10),
9, 0)
Next cell
Application.ScreenUpdating = True
End If
End Sub

On some occasions values in rng are not found in rng1 so #N/A is returned.
On these occasions I would, if possible, like to draw the users attention to
these values. I would like to have a message box listing the values, or if
this is too much, a simple message saying that certain values were not found
(perhaps these values could then be highlighted). I would prefer to do this
with conditional formatting.

Thanks in advance.
