A button that will open a gui?

Im trying to create the following, when you press the button the shop gui will appear. I have been trying plenty of hours with different code

script.Parent.ClickDetector.MouseClick:connect(function(pl)
if pl.PlayerGui.Buyshop.Frame.Visible == false and pl.PlayerGui.colorgui.Frame.Visible == false and pl.PlayerGui.cook.Frame.Visible == false and pl.PlayerGui.Sellshop.Frame.Visible == false and pl.PlayerGui.awardlist.Frame.Visible == false then
pl.PlayerGui.Buyshop.Frame.Visible = true
pl.PlayerGui.Checkopen.Value = true

pl.PlayerGui.swoosh:Play()
repeat wait(.0000000001)
pl.PlayerGui.Buyshop.Frame.Position = pl.PlayerGui.Buyshop.Frame.Position + UDim2.new(0.2,0,0,0)
until pl.PlayerGui.Buyshop.Frame.Position == UDim2.new(0.4, 0,0.18, 0)
pl.Character:findFirstChild("Humanoid").WalkSpeed = 0
end
end)

Thank you, best regard ca40

If this is in a server script, the server cannot access the PlayerGui, as it is empty for it.

The best way to get around this is to use remote events. Hope this helps!

I answered this guy a similar question: https://scriptinghelpers.org/questions/65372/why-isnt-this-remote-event-not-firing It will probably help you! You just need to change some lines.
