In Design Mode, click in an empty cell and click Lookup on the Objects toolbar.
An empty lookup object is displayed.
Double-click the lookup object.
Specify this information:
Name
Optionally specify a name. By default, lookup objects are automatically named Lookup[n]
where n is a sequential number. If you specify a name it can be easier to reference
the lookup object in formulas and scripts.
Value
Specify a formula or cell reference to display the list that is displayed when you
click the lookup. For example, specify a MEMBERGET formula.
Formula for empty result
By default (empty) is displayed if a lookup does not return any data. Optionally,
specify a different text such as ="Please select....", for example.
Tooltip
By default, the value displayed by the lookup is used as a tooltip. Optionally, specify
a different value, such as ="This is a list"
Select an icon to help to indicate the purpose of the lookup.
