Sorting Value Lists

[JAC23]

Is there a way to sort a value list, displaying only one item, other than the alphabetical default? The value list is based on a field from a table. I have the relationship sorting, but it makes no difference in how the list is displayed.

A relationship has no effect on a value list's sort order. Defining whether to include and sort the value list by a second field, however, does.
