3DS Max Transform Gizmo

Hey, Simple question...but I can't figure it out. My Transform Gizmo now only lets me move or scale my objects on 2 axis' I must have clicked something or hit a quick key by mistake. Could someone please help me as it is making modeling difficult because I have to use the other views to move my objects along the 3rd axis...Thank you, you're a life saver

I was searching for this as well and posted here since this was the first result for google.

You hit the X key to toggle it back and forth. I was stuck with that for a few days myself.
