Comparing String to Current Players

[MexicanR]

I have a chat command in which the player has to supply another as an argument and I want to be able to take the argument and compare it to a table/list of current players on the server, so that I can make sure the player is "valid". Any ideas? I was going to do the following but I know [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/player/GetHumans]player.GetHumans[/url] returns a table like this: 1 = [Player][1][Drakehawke]. I didn't know how to only retrieve the player's nick.

function ValidPly( ply )
   local tbl = player.GetHumans()

   if tbl[string.match( ply, "^.*$" )] then
      return true
   else
      return false
   end
end

local function GetNickNames()
    local tab = {}
    for k,v in pairs( player.GetHumans() ) do
        tab[v:Nick()] = true
    end
    return tab
end

local function ValidPly( ply )
   local tbl = GetNickNames()

   if tbl[tostring( ply )] then -- I guess you could try looping through the table doing string.find if you're intending to check all the keys of the table
      return true
   else
      return false
   end
end

Mostly with bad answers that probably won't work though :v:
