Dynamic values between <select> JS & ASP

[Mhtml]

Hi, I'm using an asp script to get all the folder names and file names in a directory and create a selection form from it.

How would I go about moving values from one select form to another?

If for some reason you need to look at the ASP script here it is..

<%
Dim fso, f, f1, fc, s, fk, f2, l
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder(Server.MapPath("."))
Set fc = f.SubFolders
For Each f1 in fc
s = s & "<option>" & f1.name & "</option>"
Next

Set fc = f.Files
For Each f1 in fc
s = s & "<option>" & f1.name & "</option>"
Next
%>
<select size="12">
<%=s%>
</select>

Do you want two List boxes, one pre-filled when the page loads and that when you click one value from the first listbox, the option should be deleted from the first one and the second one should be populated with that value??

Is this what you mean??

you hit the nail on the head, although I prob. should have mentioned they should be moved (deleted , recreated) by clicking buttons.

<input type="button" name="add" value="add">
<input type="button" name="remove" value="remove">
