From SchoolBase version 4.1 onwards, lookups can all be accessed from the same form, so this form is no longer needed. Please use Forms and Reports to set up Lookups_DN as a menu item, probably in your Data Manager menu, then when you have time, remove the old menu items for individual lookup tables from your menu as they are no longer needed.

Original help below for those still running SchoolBase 3.X

Lookup Forms is a very important form which usually resides on the Lookup Tables menu. This displays a list of lists which you can edit to suit your own school and which provide the contents for many of the dropdowns within the system. Forms can be made to appear on this list by selecting Lookups in the Menu box on the Forms and Reports form.

However, some of these lists have now become generic and each use the same basic form which is called List. The OpenArgs value in the Forms and Reports record determines which one appears. To aid selection there is a context sensitive drop-down from which you can select the option you require.

The Systems Manual gives greater detail about the properties of individual forms.
