I am trying to make some changes in the contacts module through studio. specifically, I would like to take 3 existing fields, remane them and then create drop down lists to be associated with them. I am able to go in and make some changes but when I hit save everything reverts back to how it was originally and none of my changes are recorded. Help! The version I am working on is 4.5.1d (build 1273).

Thanks in advance.
