How Do i script a Play button that teleports you to 1 - 5 parts?

I tried coding it out but I failed miserably.

I do not know what you mean by 1-5 parts, but I do happen to have the code for the start button and a starting menu if that would be any help. Ok, here's how you do it:

First, you find StarterGui in Explorer.

Then you ctrl click (if on mac) on StarterGui and go to insert object.

Insert a ScreenGui.

I named this ScreenGui "StartingMenu"

Next ctrl click StartingMenu and insert object: Frame

I named this frame "Background"

You can orient this frame however you like but I like to make it full screen

ctrl click on Background and insert object: TextButton

I named this button "PlayButton"

Then, ctrl click on Background once more and insert object: LocalScript (NOT JUST SCRIPT)

I named this LocalScript "MenuScript"

Now we can start scripting:

--these are the variables that we will need
DaScript = script.Parent.MenuScript
Frame = script.Parent -- this is the background
Play = Frame.PlayButton --I named the PlayButton "Play" for simplicity
GUI = script.Parent.Parent

--Now we make function PlayClicked()
function PlayClicked()
	wait(0.5)
	GUI:Destroy()--hides the GUI
end

Play.MouseButton1Click:connect(PlayClicked)
