MMF Help!, Problems with talking to NPC's

[Chrismonster]

Hey, Im trying to make a top view adventure game. I made it so when u press the SHIFT key you talk to people. And I'm usi text string or whatever... Problem is that I can't find out how to make it so when it's the last "paragraph" of the text and you press SHIFT again it closes.. I just don't get how you can do that..
(Sorry, if its hard to understand my problem.. Im just really bad at describing things:-P)

A lazy way to do it would be to just make the final paragraph blank.

[Chrismonster]

yeah, I know..: But how do I make it so that the final paragraph that is blank is destroyed when I press the button again?

Does anyone know about any Zelda Text engine tutorials or something :-P
