Adding new record to existing database table with a form

[Mongoloid]

I'm building a database that logs and tracks inbound shipping containers and I'm trying to build a form to add new containers to the main table for display in the summary tab of the dashboard. The issue I'm running into is that whenever I click the "add new" button it opens the form with data from the table pre-filled in the boxes. How do I make it so the form opens blank and when I click the "Save/Update" button to add the new record it adds the record in sequence instead of somewhere in the middle?

It's worth mentioning that there are some 350 records already in the database so finding one that's out of place takes some time.

On the Data tab of the form's property sheet set Data Entry to Yes.

Thanks Norie, that did the trick. I know it's probably a silly question, but I'm still pretty new to Access, is it possible to specify that in the event there is a selection in a subform on the dashboard, that, that containers data be populated into the form?
