Access 2007 VBA DCount() problem

I'm using this code:

If DCount("[Part_Number]", "Etching_Schedule", "[Part_Number] = 'Me.txtPart_Number'") > 0 Then
            MsgBox "That part number already exists for that date and shift."
End If

The code executes without error.  That part number does exist and it should go to the message box, but does not.

If I change the > to =, the message box does come up.

I don't understand why it is not finding the matching record.

Thanks,
Brooks

if  [Part_number] is Text Data type, use this


If DCount("[Part_Number]", "Etching_Schedule", "[Part_Number] = '" & Me.txtPart_Number & "'") > 0 Then
            MsgBox "That part number already exists for that date and shift."
End If


if  [Part_number] is NUMBER Data type, use this


If DCount("[Part_Number]", "Etching_Schedule", "[Part_Number] = " & Me.txtPart_Number) > 0 Then
            MsgBox "That part number already exists for that date and shift."
End If

Me.txtPart_Number  must be aoutside the double quotes for it to be evaluated

Would you provide an example for the DATE data type?
