Linked values

Hello !

I'm already working with SW 2012 in two computers: Home & work.  I know that "link values" is beeing replaced by "global variables". However, "link values" funtionality is still available, as far as I know.  Infact, at work I found it by click on right button on dimension. The point is that I cannot find it at home computer !!!   The only difference is that at work I have installed SW 2012 - 64 bits, and at home SW 2012 but 32 bits. Might it be the reason? Or there is something at Options menus, to make it visible this option of "link values" ?????

Thank you very much.
