Gossip button code box

[kerovi]

Hello,

Does anybody know how can I actually trigger a code box when pressed on gossip menu button where you can TYPE stuff? It looks like ImageShack® - Online Photo and Video Hosting

And where can I actually script the stuff that will happen after I press accept, example if I write down the player's name I want it to teleport me to him. < Where can I code that?

If possible provide example script link if you got it. Thanks in advance!
