I had been using SW2011 for a while we upgraded to SW 2104 SP5.0. I am used to using linked dimensions and suddenly seems they have been replaced with global variables? I tried to create a global variable by placing an "="  sign , and them typing a name, then clicking the global icon that had appeared, then clicking the check mark..nothing...tried again by just clicking check mark...it asks if I want to create a global variable, I click yes....then nothing happens. I did not get the red summation sign I was used to seeing with linked dimensions..I watched youtube videos and I'm doing exaclty like thay show, but It just won't work.  I googled some more and one link said I had to enclose in quotes, but that doesn't work either. Any ideas? thanks in advance...
