problems with basic lua

[zassadgh2]

I am trying to make a script where you can open a website on a player, it works fine when using a string inside code, but cannot get it to read from a local.

local CATEGORY_NAME = "Other"
local urlname = "http://facepunch.com"

function ulx.openurl( calling_ply, target_plys, urlstring )
	local affected_plys = {}
	for i=1, #target_plys do
		local v = target_plys[ i ]
		v:SendLua([[gui.OpenURL(urlstring)]])
		table.insert( affected_plys, v )
	end
	ulx.fancyLogAdmin( calling_ply, "#A opened #s on #T", affected_plys, urlstring )
end

local openurl = ulx.command( CATEGORY_NAME, "ulx openurl", ulx.openurl, "!openurl" )
openurl:addParam{ type=ULib.cmds.PlayersArg }
openurl:addParam{ type=ULib.cmds.StringArg, hint="www.google.com" }
openurl:defaultAccess( ULib.ACCESS_ADMIN )
openurl:help( "Open a url on a player - !openurl" )

so to execute it:
!openurl 'name' google.ca
It works fine if I replace v:SendLua([[gui.OpenURL(urlstring)]]) with v:SendLua([[gui.OpenURL("www.google.com")]]), what am I doing wrong here as I want the string from urlstring?
I get this error when using the urlstring as a parameter.

[ERROR] LuaCmd:1: bad argument #1 to 'OpenURL' (string expected, got nil)
  1. OpenURL - [C]:-1
   2. unknown - LuaCmd:1

Try something like this:

function ulx.openurl( calling_ply, target_plys, urlstring )
	for _, v in ipairs( target_plys ) do
		v:SendLua( [[gui.OpenURL("]] .. urlstring .. [[")]] )
	end
	ulx.fancyLogAdmin( calling_ply, "#A opened #s on #T", urlstring , target_plys )
end

local openurl = ulx.command( CATEGORY_NAME, "ulx openurl", ulx.openurl, "!openurl" )
openurl:addParam{ type=ULib.cmds.PlayersArg }
openurl:addParam{ type=ULib.cmds.StringArg, hint="www.google.com" }
openurl:defaultAccess( ULib.ACCESS_ADMIN )
openurl:help( "Open a url on a player - !openurl" )

Also you may want to add ULib.cmds.takeRestOfLine in your second param
