    1. CONot an answer to your question, but when trip_num == TRIP you say it's invalid but then accept it.

    3. COI'm not sure I see where I accepted that. the S M L N... are the selections to chose from the printf thats what the user was going to enter at the scanf area_code and area_code was where I was going to store the single character

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
