Why doesn't this work? [LUA]

[Jinx]

Hello, so I'm learning the basics of networking for LUA and so I'm following this tutorial. You can see at the time the video is at, I've copied all of that exactly and I'm getting an error. I just don't understand because he doesn't get the error when he loads his script.

clientside:
local frame = vgui.Create("DFrame")
frame:SetSize(300, 300)
frame:SetVisible(true)
frame:Center()
frame:MakePopup()

local b = vgui.Create("DButton", frame)
b:DoClick = function()

net.Start("MessageName")
net.SendToServer()

end

and serverside:
util.AddNetworkString("MessageName")

Thanks for the help.

b:DoClick -> b.DoClick

You can either do function b:DoClick() [..] end or b.DoClick = function( self ) [..] end.
