Please help, Vgui error with chatbox.

[jackmeep123]

It runs just fine with gcompute, but as soon as i put it on the server, it spews out an error which i put here at the bottom of the code.
It works fine when i reload the lua file.
Here is a pastebin link for line numbers: [url]http://pastebin.com/8Vaz3MiN[/url]
Any help would be appreciated.

    local widthcalced =  ( 1920 - num ) / 1920
    return ScrW() * widthcalced
end
 
local function calcH(num)

    return ScrH() * heightcalced

 [ERROR] addons/nullclientplugin/lua/autorun/client/cl_nullbox.lua:23: attempt to index field 'dFrame2' (a nil value)

[Pugsworth]

You're trying to create vgui before it's initalized, thus, dframe2 is set to nil because vgui.Create returns nil.

When you work with vgui, you need to delay the execution of your code until at least the client has began drawing the first frame.

This can most easily be done using the gamemode "Initialize" event hook, as this is called when the gamemode has finished loading and starts.
