cant add mesh? no layers?

I am having some problems. I can not add a mesh and the layer tab is not showing. In edit/object mode the layer tab does not appear. How can i get the tab to appear?

For some reason on this one blend file i cant add a mesh. I click add>click mesh>UV sphere(UV sphere is just an example), but the sphere does not appear, i cant click X and delete it, cant size it or anything. Does anyone know how to fix this?


It sounds like you are in Local mode - try pressing numpad /.

Best of Luck!

Thanks a lot man, it worked.
