Concepts on hiding and unhiding objects/fields on forms

[rjolda]

HI All,
Trying to understand the concepts of hiding / unhiding fields and objects - drop lists and Option boxes.
On Update form - some records allow an entry to be picked from an option box or a drop list and some do not.  How do it hide / unhide option boxes and drop lists depending on the record being updated?
THanks,
Ron Jolda
