Custom DFrame with Command error

[jacobcooper18]

hook.Add( "PlayerSay", "Crate", function( ply, text, public )
	text = string.lower( text )
	DFrame1 = vgui.Create( "DFrame" )
	if ( text == "!crate" ) then
    DFrame1:SetPos( 5, 5 )
    DFrame1:SetSize( 500, 500 )
    DFrame1:SetTitle( "Startup" )
    DFrame1:SetVisible( true )
    DFrame1:SetDraggable( false )
    DFrame1:ShowCloseButton( true )
    DFrame1:MakePopup()
		return ""
	end
end )

I was trying to make a DFrame that opens up when a player types !crate. But the hook dosent seem to work! Please help!

PlayerSay is a serverside hook. Anything to do with vgui is clientside. Use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/GM/OnPlayerChat]GM:OnPlayerChat[/url] instead.

Alternatively, you could use the net library, but to save yourself from unnecessary networking, it's probably best to use OnPlayerChat.
