I've tried countless times on making the GUI go to a different position. I've checked Roblox tutorials and seen that my script is correct. Please help out... it's been 3 hours.
SCRIPT
script.Parent.Position = UDim2.new(0, 200, 0, 100)

And yes I've checked the output. Didn't say anything about it...
Tried making a game place for it.. didn't work...
(P.S I just started out with learning guis..)

Try using a LocalScript, as guis should be handled with these. Also I'm not sure why would you make a script with only a line of code that changes the position, rather than changing it manually in the properties window?
(started learning guis) I'm just tryna learn the basics first..
