User: make a roblox server side text button script where when clicked it will add an value called LLM_Model inside the player if doesnt exist and it will make it the value in the textbox inside the frame where the TextButton is inside of too. 
Assistant: This script assumes you have a `TextButton` inside a `Frame` which also contains a `TextBox`.  The script will check if a player's data contains the `LLM_Model` value. If not, it creates it.  Then it updates the `LLM_Model` value with the text from the TextBox.

```lua
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Assuming this script is a child of the Frame containing the TextButton and TextBox
local frame = script.Parent
local textBox = frame:FindFirstChild("TextBox") -- Replace "TextBox" with your TextBox's name
local textButton = frame:FindFirstChild("TextButton") -- Replace "TextButton" with your TextButton's name

if not textBox or not textButton then
  warn("Error: TextBox or TextButton not found within the Frame.")
  return
end

textButton.MouseButton1Click:Connect(function()
  local player = Players:GetPlayerFromCharacter(game.Players.LocalPlayer.Character)
  if not player then return end

  local playerData = player:WaitForChild("leaderstats", 10) -- Waits up to 10 seconds for leaderstats to load

  if not playerData then
    --If leaderstats doesn't exist after 10 seconds, create a new one
    playerData = Instance.new("Folder")
    playerData.Name = "leaderstats"
    playerData.Parent = player
  end
  
  local LLMModelValue = playerData:FindFirstChild("LLM_Model")

  if LLMModelValue then
    -- Update existing value
    LLMModelValue.Value = textBox.Text
  else
    -- Create new value
    LLMModelValue = Instance.new("IntValue") -- Or StringValue depending on your needs
    LLMModelValue.Name = "LLM_Model"
    LLMModelValue.Value = textBox.Text
    LLMModelValue.Parent = playerData
  end
end)
```

**Before using this script:**

1. **Leaderstats:** This script assumes you have a `leaderstats` folder in each player. If you don't have this, it will create one.  Leaderstats is a common way to store player data, but you can adapt the script to store the data elsewhere if needed (e.g., directly under the player).  Change `"leaderstats"` to the name of your data folder if different.

2. **Value Type:**  The script uses `IntValue`. Change this to `StringValue` if your `LLM_Model` should store text.

3. **Naming:** Make sure the names `"TextBox"` and `"TextButton"` match the actual names of your GUI elements.

4. **Error Handling:** The script includes basic error handling to check if the TextBox and TextButton exist.  You might want to add more robust error handling for production.  For example, handle cases where the player doesn't exist or the `leaderstats` folder can't be created.

5. **Security:**  Always sanitize any user input (the text from the TextBox) before using it in your game to prevent exploits.  This is crucial for security.

6. **Server Script:** This script **must** be placed in `ServerScriptService` for it to function correctly.  Client-side scripts cannot directly modify player data.


Remember to replace `"TextBox"` and `"TextButton"` with the actual names of your UI elements.  This improved version is more robust and handles potential errors more gracefully.  Always prioritize security when handling user input in Roblox games.

User: this is a server side script so you cant get the user using local player also dont put it in leader stats, put it in the player itself
