Visible problem on loading swf


so my problem is

i have written this in the third frame on my ‘‘loaded’’ swf : _root.menubtn._visible = 0;

but it does not work.(keep in mind that my ‘‘menubtn’’ is on my main swf, not in the loaded one). the same script works fine as long as it’s in the very same swf. why is that?

any help :frowning:
