[quote:2thuwlzu]GetToken(string, N [, delimiter])
Returns the Nth token in string using delimiter. The default delimiter is comma (,) if you do not specify your own. Examples: GetToken("a,b,c", 2) gives "b", GetToken("one|two|three|four", 2, "|") gives "two"
You could use that, but I think you would have to force a delimiter when the person is typing in the editbox.
