Why won't .Changed for a string value work?

I want to make a local script run a function when the value of a string value called "EquippedWeapon" is changed. Here I have a local script which changes the string value upon a TextButton being pressed

01local EquippedWeapon = game.Players.LocalPlayer:WaitForChild("EquippedWeapon").Value
02 
03Buttons = {
04    script.Parent.Katana -- Katana is the TextButton
05}
06 
07 
08 
09Buttons[1].MouseButton1Click:Connect(function()
10    EquippedWeapon = "Katana"
11    wait(1)
12    print("EquippedWeapon")
13end)

Now, here's a local script in StarterPlayerScripts which runs a function when EquippedWeapon's value changes.

1local Player = game.Players.LocalPlayer
2local EquippedWeapon = Player:WaitForChild("EquippedWeapon").Value
3 
4EquippedWeapon.Changed:Connect(function()
5    print("Equipped Weapon value has been changed.")
6end)

What should happen is that when EquippedWeapon's value is changed to "Katana", it should print a message. But the error message is this:
"Players.trapiz.PlayerScripts.GearChecker:4: attempt to index field 'Changed' (a nil value)"

Thanks :)

Events only work on Instances, not strings/numbers/booleans. The Value of a StringValue returns a string, which does not have an event.

You should do Player:WaitForChild("EquippedWeapon") instead of Player:WaitForChild("EquippedWeapon").Value.

I tried it, and there's no error, but it doesn't print the message that should print when the value changes. trapiz 4 — 5y

Change "EquippedWeapon = "Katana"" to "EquippedWeapon.Value = "Katana"" and see what happens BrockRocksYourSocks 48 — 5y

Yep, that's probably the issue. Happens to the best of us. Fifkee 2017 — 5y

The variable EquippedWeapon includes .Value at the end, so that can't be the problem. trapiz 4 — 5y

Use EquippedWeapon.GetPropertyChangedSignal("Value"):Connect(function() instead of .Changed.

That doesn't work either. trapiz 4 — 5y

Remove "Value" in "local EquippedWeapon = Player:WaitForChild("EquippedWeapon").Value" unpurrity 4 — 5y
