GUI that displays health?
I'm trying to change the text of a Textbox every 0.1 seconds but i keep ending up with this error. 19:21:44.656 - Players.Player.PlayerGui.ScreenGui.PS.TextBox.Script:3: attempt to index local 'plr' (a nil value) 19:21:44.657 - Stack Begin 19:21:44.657 - Script 'Players.Player.PlayerGui.ScreenGui.PS.TextBox.Script', Line 3 19:21:44.658 - Stack End
1 | local name = script.Parent.Parent.Parent.Parent.Parent.Name |
2 | local plr = game.Workspace:FindFirstChild(name) |
3 | local health = plr:FindFirstChild("Humanoid").Health |
4 | local text = script.Parent.Text |
5 | while true do |
6 | text = health |
7 | wait(0.1) |
8 | end |
Thanks

Just a few errors in assinging your variables. I fixed it for you:
01 | --Locals took out, since they are not in the same scope in the loop. |
02 |
03 | name = script.Parent.Parent.Parent.Parent.Parent.Name --Just double check to make sure you have the right amount of "Parent"s. |
04 | plr = game.Workspace:WaitForChild(name) --WaitForChild is better in this situation. |
05 | humanoid = plr:FindFirstChild("Humanoid") --Health is in the humanoid, not the player. Also, you're setting the variable to the player's at that time, not the actual property itself. |
06 | text = script.Parent --Once again, you're setting the variable to the text of the GUI object, not the property itself. |
07 | while true do |
08 | text.Text = humanoid.Health |
09 | wait(0.1) |
10 | end |

The only thing I see that could have been messed up is that you used a string value while searching for an object, now I may be wrong, but try this alternate code, be sure to use a LocalScript:
1 | local plr = game.Players.LocalPlayer.Character |
2 | local health = plr:FindFirstChild("Humanoid").Health |
3 | local text = script.Parent.Text |
4 | while true do |
5 | text = tostring(health) --It is a number value, we need this so it can be converted to text. |
6 | wait(0.1) |
7 | end |
