• his Supplier in Taipei where the goods are to be collected from
  • Choice 1: an automatically updated drop-down list of previous suppliers he has used or
  • Choice 2: if supplier not found - Add New Supplier -a number of entry fields. The first is the text input that will appear next time in the drop-down, i.e. Supplier Name (no two can be the same), and the next will containing the address, telephone, fax and e-mail details of the new supplier
  • If PFE use Add Order, as Administrators of PFETrack, their drop down should contain all suppliers used by all Importers in the system.
• select one from a drop-down of Shipping Agents. In the unlikely event he doesn't know which Agent to use, there will be a link to the 'Shipping Agents' part of the website where he can look and learn. If he does this, the system should prompt him to save any new data he has added up to now (Can anybody suggest a better/easier way to do this?).
