My script is not working, I'm trying to setup a script with a number value, why is it not working?

Your first line is wrong, as I can see an easy error:

 brick = script.Parent guiText = game.Players.LocalPlayer.PlayerGui.ScreenGui.Frame.TextBox.Text localTeam = script.Parent.Parent.Parent.Teams.Janitors phLevel = script.Parent.PHLevel.Value 

This tries to do too much I can't even understand it.

Try this instead [I hope]

local brick = script.Parent.gui
brick.Text = game.Players.LocalPlayer.PlayerGui.ScreenGui.Frame.TextBox.Text

local Team = game.Players.LocalPlayer.Team
local phLevel = script.Parent.PHLevel.Value

function onClicked() -- no need for a playerWhoClicked argument unless it's on the server.
if Team == "Janitor" then
	-- code to do if the player is on the janitor team.
else
	print("Not on the Janitor team")
end
script.Parent.ClickDetector.MouseClick:connect(onClicked)

Some info:

Make sure your script is a LocalScript. This is because it's just easier to work with when using Guis. If you use FE, be sure to add some RemoteEvents and then you'll be able to run server things like updating DataStores [for money] and whatnot.
