--script inside of workspace

wait(5)
game.ReplicatedStorage.RunLocal:InvokeServer(game.Players.EpicStealth7, "coolscript", [[print("hi world")]])

--my plugin

on = false
print("plugin loaded")

if game.ReplicatedStorage:FindFirstChild("RunLocal") then
game.ReplicatedStorage.RunLocal.OnServerInvoke = function(player, lname, lsource)

LScript.Name = lname
LScript.Source = lsource
end
end

local toolbar = plugin:CreateToolbar("script builder stuff")
