Attempt to index a nil value?

I tried editing my script to make it fix, but it doesn't. The script works fine for the first part, but when you click the button after resetting, it pops up 21:04:40.265 - 1 is not a valid member of Frame 21:04:40.265 - Script 'Players.Player1.PlayerScripts.LocalScript', Line 16 21:04:40.266 - Stack End

1player.ToolN3.Changed:connect(function(Change)
2    if Change == "None" then
3        gui:FindFirstChild("3")["Click"].Disabled = true
4    else
5        gui:FindFirstChild("3").TextButton.Text = player.ToolN3.Value
6        gui:FindFirstChild("3")["Click"].Disabled = false
7    end
8end)

This function seems to have your issue. Specifically, one of these two lines below:

`1`	`gui:FindFirstChild("3").TextButton.Text` `=` `player.ToolN3.Value`

or;

`1`	`gui:FindFirstChild("3")["Click"].Disabled` `=` `true`

Usually the debug statement "Attempting to index a nil value" is pretty self explanatory. You tried to screw with a value that is literally non-existent.

So your best chance is to figure out what the two lines of code I listed above are doing to your script and why they are considered non-existent. You didn't provide much context on these two lines of code, so this is my best answer.

What else would you like so you can see all of the context? Decemus 141 — 9y

There are no errors anymore with the :WaitForChild, but now the text isn't getting changed. Decemus 141 — 9y

It is waiting for a value that is existent. Decemus 141 — 9y

I would like to know if ToolN3.Value is the Value of a Value named ToolN3 or is just the directory leading to a Value. If Value is the name of the Value, say Value.Value for the directory, as you're only indexing the name and not the Value property of the Value. konichiwah1337 233 — 9y

ToolN3 is a StringValue Decemus 141 — 9y

I'm going to have to go further into this by checking each object involved in the script, which will probably take forever. (Time I don't have.) .. Sorry, I tried my best. Try some solutions in your head, maybe one of them will solve your issue :) konichiwah1337 233 — 9y

By the looks of things, gui['3'] doesn't exist. Your error doesn't quiet line up with your code, so I've taken my closest guess.

If in doubt, use WaitForChild.
