"GetEquippedTool is not a valid member of Humanoid "Workspace.qw3rty_l0l.Humanoid""

It seems like you're getting an error because the function `GetEquippedTool` is not a valid member of the `Humanoid` class. Instead, you can check if the tool is equipped by using the `FindFirstChild` function on the player's character. Here is the corrected script:

```lua
local ball = script.Parent.Parent
local kickAnimation = script.Animation
local toolName = "Shoot" -- replace this with your tool's name
local proximityPrompt = script.Parent

local function onProximityPromptTriggered(player)
	local character = player.Character
	if character then
		local humanoid = character:FindFirstChild("Humanoid")
		local tool = character:FindFirstChild(toolName)
		if tool and tool:IsA('Tool') and tool == player.Character:FindFirstChildWhichIsA('Tool') then
			if humanoid then
			print(player.Name .. " has triggered the proximity prompt with the correct tool equipped.")
			ball.Anchored = false
			proximityPrompt.Enabled = false
			humanoid:LoadAnimation(kickAnimation):Play()
			local direction = (character.HumanoidRootPart.CFrame.LookVector * 25)
			ball.Velocity = Vector3.new(direction.X, 10, direction.Z)
			player.Character.Humanoid.WalkSpeed = 0
			wait(1.2)
			proximityPrompt.Enabled = true
			ball.Anchored = true
			player.Character.Humanoid.WalkSpeed = 16
		end
		end
	end
end

proximityPrompt.Triggered:Connect(onProximityPromptTriggered)
```

This script checks if the player's character has a child of type 'Tool' and if that child is the same as the tool you specified. If both conditions are true, then the script will execute the rest of the code.
