sorry...

I have a contact selector. Its content becomes a textbox's value. If I
select a user (John), John's accountID gets store in the textbox. Now if I
add another user (Tom), now the text box will have John & Tom's accountIDs.
How can I compare the previous textbox value (John) to newer value (John &
Tom) and extract Tom?

extract = store that value in another textbox
