To select a contiguous group of items, hold the [Shift] key down and select the first item, then the last item.

Description

To control the minimum and maximum number of items that can be selected, do one or both of the following:

Set the Field Syntax to REP, for example REP(1-5) (minimum is 1, maximum is 5)
Set the Field Interface to use subfields, for example VC5(50) (total length of the selected items must fit in the field length)

Although it is possible for the user to choose multiple items, if more than the allowed maximum number of items is selected, when leaving the field, the user will get the following error:

Error 0130 - Error on field
		<FldName>; too many subfields specified.
