Frame 3: Wait for User Input

Here we check to see if the user has changed what s/he typed since the last time we checked. If the have, we clear the list (by removing all the duplicate buttons--except the original one). We also set the position of the scrolltarget (the single object which is a movieclip containing ALL the buttons, whether they are duplicated or not.) We set it back to 0. We do this because... say you shows ALL links. Then you scrolled way down to the bottom of that list. Now you start typing and filter the links down to only two or three. They will be way above your viewing area... way up off the top somewhere and you will get a blank list. You'd have to scroll way up to see them. To work around this I simply reset the scroll to the very top item each time the user types anything.

If ((findit ne oldsearch) and Length(findit)>=/:minimum_search)

This only runs if we have more than (minimum allowed) characters. Otherwise... (see below) we simply show the entire list.

Set Variable: "q" = 0
Loop While (q
We go to Frame 2, the filtering script, and
see if the new input (whether more or less than the previous input) has any
matches. This way it doesn't matter if you are typing or deleting it will work
either way.

We show the entire list by going back to
Frame 1, where we initially set up the entire list.

 Go to and Play (1)

End If
Set Variable: "oldsearch" = findit
