GUI Openning + Textlist Help

[Astram]

Hey, I have a question. You may have known me before, but I left for around 1 year. Now I am back and I am deciding to script again, however forgetting some things. However, on a GUI I'm working on, when I say /test the first time, the GUI opens. However, after I "X" out, the second time I try, it doesn't open. I am calling the GUINAME.open(); event too, because I think that is how you do it, if I remember correctly but I just can't remember 100%.

In this GUI I also have a text list. However, I don't know how to get the selected row from the TextList and use it on text. For example, I don't know how to take Archer from a selected text list, and show up in the same GUI as "You selected: Archer". I think this is because it won't update it I believe until you re-open it. But then the selected text will be gone, so please give me help on these 2 things!

Thanks!
