1996 corolla 5 speed quit going into gear need help where to start

#1
Like i said i have 1996 corolla 1.6 5speed that slowly quit going into gear one day. The pedaI went to the floor pretty much by the time i got it home. I managed to limp it home and checked the fluid and it was fine. I also adjusted the clutch pedal to the max and it still wont go into gear. I'm wondering if it is the master cylinder or the slave cylinder?
