You're trying to build a rocket ship before learning how to make a wheel. If you have little to no scripting experience, might I suggest checking out some of these links I have posted in an answer here. https://scriptinghelpers.org/questions/9539/#12184 

Scripting Helpers is not a request site, we'll be able to provide and explain wiki articles to help you get what you want to achieve, we can not provide you a final script. Please, one topic at a time so we may gear answers toward that single topic. Please ensure you put detail in your questions and what you know about the topic you're aiming for.

ok but can you help me with the script for the teleporting dialog?
