[ERROR] lua/testing.lua:1: attempt to index global 'vgui' (a nil value)

[Siniq]

Hello everyone,

im sorry for this being my first post and immediately start asking questions, but i just started lua in gmod13, did some lua in gmod12 before.
now im trying to create my GUI in singleplayer, like i did in gmod 12 but i stumbled upon a small error.

[B][ERROR] lua/testing.lua:1: attempt to index global 'vgui' (a nil value)[/B]

since i just started after quite some time doing nothing with lua, im using the wiki to help me out.
i made a folder in my gmod client directory called 'lua', and placed my script 'testing.lua' inside it and im trying to run it with the command: lua_openscript testing.lua

and now it cant seem to find the vgui library?

this is my code, in case i screwed up on that.
Pulled it right off of the wiki so i guess the code isn't causing the failure.

local DermaPanel = vgui.Create( "DFrame" )
DermaPanel:SetPos( 100, 100 )
DermaPanel:SetSize( 300, 200 )
DermaPanel:SetTitle( "My new Derma frame" )
DermaPanel:SetVisible( true )
DermaPanel:SetDraggable( true )
DermaPanel:ShowCloseButton( true )
DermaPanel:MakePopup()

Can someone point me out what i am doing wrong?

Many thanks,
Siniq.

You are loading the code serverside. The vgui library is clientside.

If you are using lua_openscript you should be using lua_openscript_cl.

Thanks for the fast reply, Lost Sandwich
but that didnt fix my problem, its not showing the error anymore, but it doesnt show my vgui when calling the script. i tried to make it a function and call that function with a concommand but then it says the concommand doesnt exist?

My code now:

function testframe()
        local DermaPanel = vgui.Create( "DFrame" )
		DermaPanel:SetPos( 100, 100 )
		DermaPanel:SetSize( 300, 200 )
		DermaPanel:SetTitle( "My new Derma frame" )
		DermaPanel:SetVisible( true )
		DermaPanel:SetDraggable( true )
		DermaPanel:ShowCloseButton( true )
		DermaPanel:MakePopup()
end
concommand.Add("testframe", testframe)

PS. This might be in the wrong section, if a mod can put it in the LUA Scripting forum, it'd be awesome! Thanks!
