When you select Append, each field is checked for errors. If an error is detected, an error message appears and the cursor returns to either the field containing the error or to the first field on the form.

Select Append again to add your corrections to the database.

If your query target is a QBFName, your customized form can contain mandatory fields, validation checks, or special attributes. These requirements must all be met before QBF allows the Append operation to add data from the form to the database.
