popup form updating incomplete records

[Jon123]

I have a popup form that user will select for updating 4 fields in table. I have a update button that has code behind it that verifies the record is complete before closing the popup form.That works well. However, I want to add an abort button that will close the form and save nothing entered however, I getting incomplete records and blank records. How can I code the button to not update the table and just close the form?
