Access - get previous record’s fields

Hi there,

I have an Access database with 1 table. I'm designing a form that has 4 fields to add records to this table. When the user first enters the fields for the day, 3 of the fields will stay the same for the rest of the day, e.g. 1 of the fields is the current date. (The database isn't used 24/7, so the form doesn't need to check if a new day has come.)

I also have a button on the form for the user to press to save the record. When this button is pressed, a new form should come up with the 3 fields already filled in with the previous record's values.

How do I go about doing this? I already have the button that uses this event:
DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70

Thank for any help! Sample code will be helpful too.
