Need some help with an idea, not quite sure how to do it but have done the foundations.

Great idea

(You need to explain and be specific. What are you trying to do? Why/where does it not work?)

{_chosen::%player's uuid%}

[frosty prawn]

what? no

if you want it to re open on close if they havent picked, use the on inventory close: event.

also, you would then need a global variable, not local.

you can also move set {_chosen} to true and close player's inventory out of the index conditions, as they are run regardless of the picked gem

hey, a little differences, I got some help on the skript and now it has 0 errors, but the gui is not opening for anyone, and the autoclose + autoreopen feature arent working

This isnt a place for you to submit code and get others to fix it — we are here to help you learn what is wrong with it. You are supposed to leave with not only working code, but more knowledge which will help you in the future

[gusty storm]

So dont fix it for me then, explain what I have done wrong, then I learn from it?

my ocd is killing me

and for the else if name of event-inventory is "PLEASE CHOOSE YOUR GEM":, just an else: would work
