Why is this script not running when i set the disabled property to false?

I am making a script where if you type "hello" and press enter in a text box, it undisables a script that adds 5 coins to a coins datastore. Here is the script that undisables the script: note: the script is in the workspace

game:GetService("UserInputService").InputBegan:Connect(function(key)
		if key.KeyCode == Enum.KeyCode.Return then
			if script.Parent.Text == "hello" then
				print("worked")
				workspace.dsactivatecoins5.Disabled = false
				local particalsuccess = Instance.new("ParticleEmitter")
				particalsuccess.Parent = game.workspace.tvscreencpp
				particalsuccess.Name = "particle"
				particalsuccess.Enabled = true
				script.Parent.Parent.Frame.text.Text = "Great job! Now click the button that says 'teleport to example' Also, here are some coins!."
				script.Parent.Parent.TextButton.Visible = true
				wait(2)
				particalsuccess.Enabled = false
			script.Parent.Parent.yaycorrect.Visible = false
			script.Parent.TextEditable = false
			script.Disabled = true
			end
			if script.Parent.Text ~= "hello" then
				print("DENIED")
				local udidbad = Instance.new("Explosion")
				udidbad.Name = "bad"
				udidbad.Parent = workspace.tvscreencpp
				script.Parent.Parent["no :("].Visible = true
				udidbad.Position = workspace.tvscreencpp.Position
				udidbad.BlastRadius = 20
				wait(2)
				udidbad:Destroy()
				script.Parent.Parent["no :("].Visible = false
			end
		end
	end)

Use this function instead:

[textBox].FocusLost:Connect(function(enterPressed)
	if enterPressed then --checks that enter was pressed.
		--Insert your code here.
	end
end)

It turns out that it is the script that is not functioning. i have tried using attributes, but I do not know how to use if statements with them
