Why wont this work?? Nothing wrong with output, it just wont work.
local player = Game.Players.LocalPlayer
local swordMesh = script.Parent
local GuiBar = player.PlayerGui.ScreenGui.TextBox --Change to correct path.
GuiBar.FocusLost:connect(function()
pcall(function()
swordMesh.Texture = "http://www.roblox.com/asset/?id="..GuiBar.Text --Try to change the texture.
end)
end)

That wont work either. Help please???
Are you sure that: 1. The script is a localscript 2. The parent of the script is the Mesh 3. Inside your player's PlayerGui there is a ScreenGui named ScreenGui and inside that is a TextBox named TextBox
I have a feeling your TextBox path is incorrect.
