How To Bring up form by dblclick in listbox

Hi all!

I am somewhat new to MS Access.  I created a database with customer info in
it.  I created a search form with a text box for typing in a last name or
part of a last name and a list box that shows all appropriate matches from
the text box.  I now want to be able to click or dblclick on one of the
appropriate names in the list box to open up the edit form for that person.
How do I go about doing this?  I have spent about two weeks researching and
tearing down a similar database only to get nowhere.  Any help would be
greatly appreciated.

Thanks
