saving list component contents as a sharedObject

[kbtdk]

Hi folks. In flash cs3, as2.0, I have a list component that is populated with the text from an input text box with a button. each time the user inputs text into the textbox, the input is added to the list, thus populating the list. my question is how do i save the list box contents as a sharedObject, so that when the page is reloaded, it has the previously added contents? and if it's not asking too much how would i be able to select an item in the list box and change the input, and then save that along with the other item(which are unchanged) as a sharedObject?
thanks in advance.
