20:47:13.183 - Players.jkiop23.PlayerGui.ScreenGui.TextLabel.LocalScript:11: attempt to index global 'TimeValue' (a number value)

this was the error

Your script is to long and because you have cut off some code your "Line 11" is actually line 6.

Heres a shorter and speedier bit of code that does the same:

local PlayerGui = game.Players.LocalPlayer.PlayerGui
local TextLable = PlayerGui.ScreenGui.TextLabel

local Time = game:GetService("Lighting").ClockTime

if Time < 13 then
	TextLabel.Text = "Time:".. Time ..":00".. "AM" .. "[Day Shift]"
else
	TextLabel.Text = "Time:".. Time - 12 ..":00".. "PM" .. "[Day Shift]"
end
