how do i Enable a screengui with a script?

I'm tying to put a comic in front of my game so that when a player first joins it will pop up I've spent an hour or two trying I've tracked it down to the part where i script enabled see:

Local imgone = game.StarterGui.imgone

Local imgtwo =game.StarterGui.imgtwo

Local imgthree =game.StarterGui.imgthree

imgone.Enabled = True imgtwo.Enabled = False imgthree.Enabled = False wait(10) imgone.Enabled = False imgtwo.Enabled = True imgthree.Enabled = False wait(10) imgone.Enabled = False imgtwo.Enabled = False imgthree.Enabled = True wait(10) imgone.Enabled = False imgtwo.Enabled = False imgthree.Enabled = False

it doesn't work

imgone stands for image one or comic one

in imgone,imgtwo, and imgthree there is a imagelabel that has my comic on. im a noob at scripting i want to now how to chang the enable value of a screengui with a script
