Has anyone had any success with this?

I am trying to turn an object off, using:

SetObjectEnabled("Blind1", false);

where "Blind1" is the object name. But I keep getting a script error saying: value was nil when getting global with name 'false'

The always helpful editor documentation says the syntax is correct altho it instructs you to place "the flag that sets whether the object will behave standadly when a hero comes to it" where I have placed the word false in my code. What the editor documentation neglects to say is what the acceptable values for that flag are. I am certain false is not an acceptable value which is why I get the error.

Can anyone help?
