How would I make this work?

I made a personal message GUI, and inside a button is this LocalScript. However, I don't know how to parent the PM GUI it makes to the recipient's PlayerGui. I did this script.

function pm()   
    local n = game.Players.LocalPlayer.Name
    local m = script.Parent.Parent.username.Text
    local b = script.Parent.Parent.pm.Text
    local p = game.ReplicatedStorage.pm:Clone()
    p.Frame.author.Text = "from " .. n
    p.Frame.text.Text = "" .. m
    p.Parent = game.Players.m.PlayerGui

end

script.Parent.MouseButton1Down:connect(pm)

I need to know how I would do line 8 correctly. Can anyone help?
