How do I keep the Gui position in the corner of the screen on different screen sizes?

I have a laptop hooked up to a monitor. when I move my studio around between the two, my Gui is in a different place. (the screen sizes are different)? How do I make it so that the Gui stays in the same position it is on my laptop on other screen sizes?

Use the scale property of size rather than offset, and your problem is solved. Beware: because it is scale, the value of 1 = 100% of the size of the parent, so if you want your Gui to be half the screen's size on both x and y axes, set them both to 0.5.
