How do I make a chat command with two players?

Alright, so I figured out how to make a command with one player, but what about two? So the command I want to make is :tp. So if you want to know how it works, say like there is two players, Loot_0, and 0_tooL. Then, I say :tp lo 0_ and I get teleported to 0_tooL.

function findPlayer(r)
    for i, v in pairs(game.Players:GetPlayers()) do
        local n = v.Name:lower()
        if n:find(r) then
            return v
        end
    end
end

game.Players.PlayerAdded:Connect(function(plr)
       plr.Chatted:Connect(function(msg)
              if msg:sub(1, 4):lower() == ":tp " then
                     local p = findPlayer(msg:sub(5):lower())
                     local p2 = findPlayer(msg:sub(7):lower())
                     if p and p2 then
                            workspace[p.Name].Head.CFrame = workspace[p2.Name].Head.CFrame
                     end
              end
       end)
end)
--Edit: Focus on lines 13 and 14
--I typed most of this on here, so there might be mistakes.

On line 13, I know it wouldn't work because if I said :tp loot 0_to, it would try to find a player called "loot 0_to". And for line 14, it also wouldn't work cause p would have to be one letter long. So, again, how would I make a chat cmd with two players?
