Mike,
On your form's design view, make sure the Wizards button is toggled ON an then put a new command button on your form. That will activate the Wizard. It will guide you into putting a button on the form that will save the data. When you do that and view the code behind it, you should see something like this on the button's ON CLICK event:
Code:
DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
