Welcome to the forum- always good to see new members.

Access can handle adding new records natively- just make sure that the form's record source is an editable query or the table itself. It sounds like the addition form is only for adding new records- if this is true, then you can make its record source be the table and set it's Data Entry property to Yes (on the Data tab of the property sheet). This will set the form so that it will not show any existing records- it only allows records to be added to the table.
