I have an unbound form that I enter a range of numbers (and other data) to populate a table.  I use a command button to populate the data.  When the button is pushed, how do I get the form to clear, so I can enter the next range of data?

I used to write code for another command button to clear a form (but those were bound forms).  Here is the code I used

Private Sub Command_Click()
If me.dirty then me.undo
End Sub

This code does not work for the unbound form.  What do I need to do?  

Thanks in advance
