Don't save changes to a record

[Tammy]

How do I code a Cancel button?? I want to close a form which is bound to a table or a query but I don't want to save changes. I have tried the following code but it doesn't work:
Docmd.Close acForm, "frmGeneral", acSaveNo.
CAN ANYONE HELP?

As long as the record hasn't been saved already by some other action, you can use the Undo command (me!undo) before closing the form. This restores the 'oldvalues' to the controls.

Me.undo
docmd.close
