[HELP] GUI Appearing when player touched Part?

Hey there,

I'm super new to scripting like REALLY new as in just started a few hours ago but feel like i understand a good lot just not to sure on how i would word certain codes in order to execute what i intend.

So ive been working on making Gui dialogs as seen in games like Camping and them other short story games.

And were i seem to find an issue is making a GUI appear when player touches a Part i've checked youtube but most seem to be broken/outdated and no longer work as intended

I've been using things like script.Parent.Touched:connect(function (hit) and other similar events but nothing seems to quite work

If anyone could point me in the right direction it would be great!, Thanks
