Incorrect errors.

I’ve just come back to unity after a short absence from scripting, and I thought I hadn’t forgotten anything at all but for some reason I cant discern this is throwing up errors;

var public xSensitivity = 10.0;

Its giving me these errors:

(1,5)Unexpected token: public.
(1,11)';' expected. Insert a semicolon at the end.

Im certain it isnt me this time, perhaps someone could shed some light on it please? Chastise me if im wrong haha.

Thanks.

EDIT: Oh, I’m using Javascript by the way

public var…not var public
