Why does this not work?
game.Workspace.CarPrice.Value = game.Players.YurStillABustaToMe.PlayerGui.CarPrice.TextBox.Text
It won't work because of Filtering Enabled. When you change the text of a TextBox, it doesn't show for the server.
Instead of inserting it into the Player's PlayerGui, you can just make a script in StarterGui.
Does a part have that script? Or is it not attached to a part?
local t = game.Players.YurStillABustaToMe.PlayerGui:FindFirstChild("CarPrice") local val = game.Workspace:FindFirstChild("CarPrice") print(t,val) while true do wait() if val and t then val.Value = t.Text end end
