Why is this not working?

while wait() do
		if script.Parent.Value.Value < 0 then
			script.Parent.Text = "You lost...restarting."
			wait(0.01)
			script.Parent.Parent.OHealth.Value.Value = "4000"
			script.Parent.Parent.OHealth.Text = "OPPONENT'S HEALTH: "..script.Parent.Parent.OHealth.Value.Value
			script.Parent.Value.Value = "4000"
			script.Parent.Text = "HEALTH: "..script.Parent.Value.Value
			else script.Parent.Text = "HEALTH: "..script.Parent.Value.Value
end
	end

1. i don't think using while wait() do is correct. You should put a true or false value or a value ><= so the loop goes on until the value changes.

2. when you set a health value you don't need to put "" you just write the number. For example: OHealth.Value.Value = 4000 and not OHealth.Value.Value = "4000". Unless it's a text or a stringvalue.

3. script.Parent.Parent.OHealth.Text = "OPPONENT'S HEALTH:""..script.Parent.Parent.OHealth.Value.Value.."" <---- Correct way of writing it
